Abstract:
Purpose. Development and generalization of a set of key elements for a non-waste technology concept of mining high-quality coal from thin coal seams, based on the processes of backfilling the mined-out space with waste rocks from stope and tunneling operations. Methods. A comprehensive methodical approach, containing the systematization and generalization of the constituent elements of a non-waste coal mining technology based on the implementation of theoretical studies and substantiations, is used in the research. Findings. The main hypothesis of a new approach to non-waste coal mining has been formed, in which the priority is not only the process of leaving the maximum waste rock volume in underground cavities, but also its use to form backfill mass, thereby improving the geomechanical conditions for mining thin coal seams. A wide range of mining tasks has been formulated and systematized for using a non-waste coal mining technology. The conditions for the harmonious functioning of the proposed conceptual scheme of a non-waste coal mining technology within the extraction field boundaries have been determined and substantiated. The conceptual foundations for the functioning of a new highly efficient non-waste technology for mining high-quality thermal coal from thin coal seams have been developed. Originality. The scientific novelty is in revealing the mechanism for the effective logistic functioning of rock-transport systems for the accumulation of waste rocks in the underground space using a non-waste technology of coal mining from thin coal seams. Practical implication. The research results can be used in planning non-waste technological schemes for mining the coal with an increased energy potential. Keywords: non-waste technology, waste mine rocks, backfill, selective mining, stope, drifting face, transportation.

Abstract:
In order to solve the problem of heaping waste in aboveground, a cleanly mining technique of waste not discharged from coal mine was proposed. It includes two key points as follows: one is waste separation underground; the other is mining technique with preset packing body of waste without coal pillars. After the waste from the coal mining face had been separated out, the waste was used to preset packing body of waste. It is able to decrease stress of mine hoisting. The technique has been successfully used in Gaozhuang Coal Mine.

Abstract:
Mother Nature has bestowed India with huge resources of coal, iron ore, bauxite, manganese and limestone. India has one of the lowest per capita availability of land due to population of more than 1.3 billion. The transformation from under developed to developed economy warrants enormous increase in mineral production. This will generate additional huge quantities of waste. The industry is already facing problems related to land acquisition and environmental clearances. Sustainable development of Indian mineral industry requires reprocessing, reuse and recycling of mine waste. To achieve this, economic and innovative mineral processing methods are required which will result in least damage to ecology and environment.

Abstract:
China is the world’s largest coal producer country. However, large-scale coal mining has led to severe environmental pollution issues such as surface subsidence and gangue piling up. The gangue discharging amount has ranked the first in the world and coal mine enterprises are facing enormous discharging reduction pressure. This paper summarizes the research progress of the solid backfilling mining technology and then illustrates the realistic demands and significance of implementing underground coal-waste separation. It also focuses on the technical principles, systems and key equipment of the common underground coal-waste separation methods, such as the selective crushing method, the dense medium shallow groove method, the vibro-assisted jigging method and full-size water separation method and ray identification method. In addition, the selection steps of underground coal-waste separation method, the design process of large section separation chamber and the design principle of separation and backfilling system are proposed, finally, the mining-separating-backfilling + X for coal mining is put forward. By combining the technology of mining-separating-backfilling with other technologies, such as gob-side entry retaining with non-pillar mining, gas extraction, solid waste treatment, water protection mining, mining under buildings, railways and water bodies, the integrated mining methods, mining-separating-backfilling + setting pillars, gas drainage, treatment, protection and prevention methods are formed. It also introduced the ‘mining-separating-backfilling + gas extraction’ technology’s whole idea, system arrangement, separation equipment and practical engineering application effects based on the specific engineering case of pingmei no. 12 coal mine. The results indicate that the integration of underground coal-waste separation and solid backfilling technology could achieve gangue discharging reduction, underground washing and surface subsidence control. It is effective at realizing green mining.

The article is devoted to the problem of safe subsoil use of the Earth in the increasingly complex mining-geological and natural-climatic conditions, the increase in the depth and scale of the developed mineral deposits of various types and phase state. It is shown that in our country such achievements in the direction of fundamental and applied research and development are related to establishing general formation mechanisms and evolution features of focal zones of increased stress concentration and destruction rock masses and geomaterials with block-hierarchical and multiphased structure; these geomaterials have properties of open self-arranging geosystems in tectonic field of stress and strain. Based on modern achievements of non-linear geomechanics and geophysics, cloud information technologies of BigData, the new (energetic) methodological approach and corresponding methods have been justified, as well as technical (measuring) means and software complexes for formation multilayered geoinformation monitoring system for diagnostics control and prediction of industrial and ecological safety at strategically important mining areas in Siberia, which has been approved in field conditions (Kuzbass, Norilsk and Novosibirsk Region).

Abstract The cataloging of over 220 coal mining dumping grounds after hard coal mining was carried out on the area of the Upper Silesian Coal Basin (USCB). Considering the significant content of coal particles in the waste, these object may be perceived as perspective anthropogenic deposits. In order to define the possibilities of recovery, an attempt of linking the quality of coal in the deposit and the in waste material was performed. Another step is the reclamation and use of dumping grounds after completing effective recovery processes. The purpose of the research was the cataloging, mapping and valorization of coal mining waste dumps from Katowicki Holding Węglowy coal mines, for the needs of reclamation and management of examined objects and defining the potential recovery of coal from the dumps. The valorization of the post-mining waste dumps was done with the use of original methodology, considering the problems of: reclamation, management, accessibility of the dumps as well as environmental hazards. T he directions of the technical reclamation (e.g. landscape objects, tabular dumps) and biological reclamation (e.g. forest direction, mixed reclamation (grass and tree reclamation), grass cultivation, lack of reclamation) were defined. Accessibility with regard to open access/closing of the dump area and the roads leading towards the object were evaluated. T he connection of coal quality in the deposits of KHW S.A. and in waste material enabled the definition and evaluation of the potential possibilities of recovery of coal from the post mining dumping grounds.

Abstract:
Plus de 50 millions de tonnes de déchets miniers de charbon (CMWs) sont générées et stockées dans la nature chaque année en Pologne. Or, l'exposition de ces déchets aux conditions atmosphériques entraîne du drainage acide minier et la production de CO2. L'objectif de notre recherche est d'étudier la faisabilité d'utiliser les CMWs comme substitut aux granulats naturels dans le béton et le mortier. Notre étude porte à la fois sur la caractérisation des propriétés des CMWs et sur l'analyse des performances du béton / mortier à court et à long terme. L'effet de la teneur en CMWs sur la résistance à la compression, la résistance à la traction par fendage et la flexion, la densité du béton à l'état durci, l'absorption d'eau, la porosité et la durabilité ont été analysé. Il a été montré expérimentalement que la résistance du mortier diminue avec l'incorporation des sables miniers CMWS. Néanmoins, l'ajout des déchets n'affecte pas significativement l'ouvrabilité des mortiers à l'état frais. Les résultats expérimentaux ont également montré que les performances mécaniques des bétons incorporant les CMWs restent dans des limites acceptables pour des applications non structurelles. Les résistances à la compression, à la flexion et à la traction par fendage du béton ont déminué proportionnellement au taux et au type de substitution (sable ou gravillons). Les résultats des essais de durabilité des bétons incorporant des CMWs ont montré d'une part, une augmentation de la porosité et une réduction de la résistance à la compression, en particulier pour des taux élevés de substitution en gravillons CMWG sous le vieillissement du béton par des cycles de gel-dégel. D'autre part, les essais de pénétration des ions chlorure et de carbonatation ont montré une perméabilité accrue aux ions chlorure, et une plus grande profondeur de pénétration du CO₂, ce qui favorise la corrosion des armatures métalliques et réduit la durabilité des structures en béton armé. Cependant, la substitution de granulats CMW à faible pourcentage (moins de 30 %) limite la diffusion des chlorures et la pénétration de CO2 à un niveau comparable à celui des bétons ordinaires. Les analyses microstructurales (MEB/ EDX) et les analyses chimiques (FTIR) ont confirmé que l'incorporation de CMW entraîne une augmentation notable des pores et de leurs connectivités, ce qui facilite la pénétration de CO2 et Cl- dans la structure du béton. Enfin, il a été montré que la résistivité électrique présente un indicateur fiable des performances de durabilité des bétons incorporant des CMW. Une forte corrélation a été observée entre la résistivité électrique et la perméabilité aux ions chlorures et à la carbonatation
Over 50 millions tons per year of coal mine wastes (CMWs) are produced and stored in various locations in Poland. Exposure of these waste materials to atmospheric conditions leads to the formation of acid mine drainage and CO2 production. The objective of this research work is to study the feasibility of using CMWs as a substitute for natural aggregates in concrete and mortar, based on the characterization of coal mining waste properties, as well as the short-term and long-term properties of concrete/mortar. The effect of CMW content on compressive strength, splitting tensile strength, flexural strength, hardened density, water absorption, porosity, and durability was analyzed. It has been experimentally proven that mortar strength decreases with the incorporation of CMW sand. However, the addition of these waste materials does not significantly affect the workability of fresh mortars. The results also showed that the mechanical performance of concrete incorporating CMWs remains within acceptable limits for non-structural applications. The reduction in compressive, flexural, and splitting tensile strength is proportional to the substitution rate and type (sand or gravel). showed, on one hand, an increase in porosity and a reduction in compressive strength, especially for high substitution rates of CMWG gravel under freeze-thaw aging cycles. On the other hand, chloride ions penetration and carbonation tests showed increased chloride permeability and greater CO₂ penetration depth, which promotes the corrosion of steel reinforcement and reduces the durability of reinforced concrete structures. However, the use of CMW aggregates at low percentages (less than 30%) limits chloride diffusion to a level comparable to that of conventional concrete. Microstructural analyses (SEM/EDX) and chemical analyses (FTIR) confirmed that the incorporation of CMW leads to a significant increase in pore size and connectivity, which facilitates the penetration of CO₂ and Cl⁻ into the concrete structure. Additionally, it was shown that electrical resistivity is a reliable indicator of the durability performance of concrete incorporating CMW. A strong correlation was observed between electrical resistivity and permeability to chloride ions and carbonation

Abstract:
Modern coal preparation facilities incorporate a wide array of solid-solid and solid-liquid separation processes for rejecting mineral matter to meet market specifications. The coarse mineral matter is typically placed into engineered refuse piles whereas the fine refuse is either stored in impoundments or co-disposed with the coarse refuse. The discharge water from the refuse material represents an environmental concern due to the potential release of trace elements, and the subsequent elevation of total dissolved solids and conductivity. The research findings reported in this dissertation addresses sustainable coal processing waste disposal through using strategies aimed at minimizing the environmental impacts. To provide an accurate and inexpensive method to assess the potential environmental effects of a given waste material, a conductivity screening-level test was modified to incorporate the impact of particle surface area. The test was used on various waste streams as well as the particle size and density fractions of each waste stream to identify environmentally sensitive components that can be separated from the bulk and isolated to prevent negative environmental impacts. The results were subsequently evaluated for long term mobility of trace elements under different disposal scenarios: (i) static leaching tests designed to simulate the quiescent conditions in a stable impoundment, and (ii) a dynamic test to simulate waste materials exposed to the atmosphere in variable wet/dry storage conditions. The results indicated that liberating, separating and isolating the highest density fractions (>2.68 SG) which represents less than 5% of the coal refuse materials results in significant abatement of total dissolved solids and conductivity. Required modifications of the coal processing plants were suggested to segregate and subsequently isolate the environmentally sensitive fractions from the remaining refuse material.

Abstract:
The depletion of more attractive thicker and easily accessible coal seams in the central Appalachia will direct attention towards the extraction of coal seams thinner than 28 in. This thesis investigates the feasibility of an integrated mining and backfilling system applicable to thin seams. Two conceptual mining systems, namely Auger mining and Self Advancing Miner, have been proposed for this purpose. Both these systems are designed to remotely mine coal from the seams. Several attempts were made in the past to mine coal in a similar fashion but were not very successful due to several problems inherent to thin seams. The lack of effective steering techniques, accurate coal/rock interface and pillar thickness detection techniques were the main shortcomings of the systems. These problems were addressed in the proposed conceptual mining systems. Several coal/rock interface and rib thickness detection techniques currently available in the market or in the prototype stage have been discussed. Recent developments in coal/rock interface detection and direction sensing techniques have good potential in alleviating the previously encountered problems. Sensitivity analyses have been performed to assess the of effect critical mining parameters on the production potential of these systems. The self advancing miner has been found to be more promising than auger mining. Conceptual panels and face layouts for both systems have been included. Two types of filling methods namely pneumatic and hydraulic are considered applicable under thin seam conditions. A backfilling technique using rubber hoses for fill placement can be applied with both methods. Sensitivity analysis have been performed to establish the relationship between face operation cost, filling cost per ton and development cost per foot. Resulting analyses indicate that panel cost per short ton of coal is more sensitive to filling cost than on development cost.

Abstract:
A large percentage of Southern Appalachian coal reserves are located in seams less than 36" thick. As thicker and currently more mineable, deposits are exhausted, methods of underground thin-seam extraction will have to be developed. These methods must be capable of removing coal efficiently and economically. Past experience with highwall mining of thin-seam coal has indicated that recovery rates tend to be lower than in conventional operations. It is suspected that this will also apply to underground thin-seam mining, regardless of proposed technology or mining method. A method of increasing recoveries from thin-seam mining operations is necessary in order to exploit thin-seam reserves. Backfilling is one alternative that may find applicability in thin-seam coal mining. The ability of backfill to provide additional ground support may enhance coal recovery by allowing for the design of undersized pillars. Backfill has been used extensively in hard rock mining but has found limited use in coal mining. Its adaptability to thin-seam coal mining has been examined and is presented in this thesis. Backfill is capable of providing additional ground support by restricting lateral deformation of surrounding coal pillars and roof. This additional support can result in significant increases in recovery from thin-seam coal deposits. However, the overall feasibility of backfill is dependent on the in situ behavior of the fill material, the properties of the fill, the effects of the filling method on the total mining operation, and the cost of filling per extra ton of coal recovered. The influence of these parameters has been studied and indicate that, in certain situations, backfilling for the purpose of increasing recovery rates from thin-seam coal mines is feasible.

This thesis presents details of investigations into the potential for co-disposal of the two rejects from Clarence Colliery and Kable's Transport Sand Mine. Column experiments were undertaken to simulate field conditions. The experiment consisted of: 1/. creating the required co-disposal arrangement and structure in containers 2/. infiltrating water through each container and measuring the rates of infiltration and overflow 3/. measuring the chemical properties of the leachate water. Geotechnical tests of co-disposal pile stability were undertaken using a specially constructed shear box. Results of this study suggest the co-disposal of course coal washery reject from Clarence Colliery with clay tailings from Kable's Transport Sand Mine is a feasible option for managing the generation of acetic drainage. It is recommended that field trials comprise layers of coal reject and clay tailings in a 9:1 ratio. Layering the coal reject with clay tailings creates a semi-permeable barrier which acts to restrict water percolation through the reject as well as reacting with the leachate to increase the leachate pH and adsorb metals

Abstract:
In this research, it is aimed to remove toxic heavy metals in waste water with the help of fly ash from Ç
ayirhan thermal power plant. The chemical and physical properties (size distribution, specific surface area, porosity, chemical composition, etc.) of fly ash were determined. The experiments were carried out in synthetic waste water containing lead, zinc and copper metals at different concentrations with the addition of fly ash. The effects of metal concentration, agitation time, particle size, ash amount, and pH in the metal removal were examined. With the addition of even very small amount of fly ash, heavy metal removal from waste water was attained at up to 99%. Fly ash particle size has no significant effect on removal of heavy metal ions from solutions. Higher solution pH and longer treatment time were resulted better metal removal. The results also indicated that the main mechanism for metal removal was precipitation due to alkaline characteristics of fly ash and more than 90 % of metals in solutions were removed by precipitation. The pH ranges for maximum metal precipitation were 10-11, 8-10, and 10-11 for copper, zinc, and lead respectively. Very small percentages of adsorbed metal was released during the desorption test.

Abstract:
Coarse coal refuse is difficult to reclaim due to high potential acidity and coarse fragment content, low water holding capacity, low fertility, and other problems. Little is known about coal refuse properties, particularly as they relate to revegetation potential. This study was undertaken to determine the physical and chemical properties of composite samples from 27 coal waste piles of varying age. Selected physical and chemical properties varied widely across this sample set. The mean coarse fragment (>2mm) content of these materials was 60%. The average texture of the fine (<2mm) fraction was a sandy loam with 15% clay. The mean water retention difference, between 0.03 MPa and 1.5 MPa of soil moisture tension, on a whole sample basis was 0.08 g water/g refuse. The pH values varied from 8.3 to 3.0, and the older piles generally had lower pH values than the more recent piles. The saturated paste electrical conductivity (EC) was higher in the younger coal waste materials. Total elemental analysis revealed that Si, Al, Fe, and K were the most abundant elements in these materials. The mineralogy of three selected samples was found to be dominated by quartz in the sand and silt fraction and mica in the clay fraction. The physical factor most limiting to plant growth was found to be low water holding capacity. Low pH was found to be the chemical factor most limiting to plant survival. These findings indicate that some refuse piles may be suitable for direct seeding, but many will require heavy lime and/or organic treatments.
