Abstract:
Backfill materials of various origin and composition, abandoned machinery, oils, PCB, gallery support material and cables are the main wastes occurring in underground coal mines during the period of their abandonment. Bearing in mind that under increasing societal pressure most if not all underground coal mines are going to close sooner rather than later, it is important to understand the interactions of these waste materials with rising mine water during mine water level rebound to prevent adverse environmental effects, especially on surface and groundwater. To this end, the composition of mine water at decant points as well as the hydrogeochemical, temporal and spatial dynamics of mine water during rebound requires quantification. In the first part of this paper, an overview of waste materials in underground coal mines is presented. The second part focusses on the experiences gained in the Ruhr area, a closed underground coal mining region in western Germany, where mine water rebound has been ongoing for decades. In this regard, the mine water modeling program Boxmodell was applied during regulatory approval procedures to predict the hydrodynamics and hydrogeochemical development of the water rebound. The results of these investigations allow deep insights into the interactions of rising mine water with wastes as well as the complex chemical evolution of mine water and potentially occurring contaminants (e.g., PCB). The experiences regarding wastes in underground coal mines and the geochemical evolution of rising mine water gained in the Ruhr area can be utilized to support the planning of mine closure in currently still active underground coal mining areas worldwide.

Abstract:
This study is focused on the possibility of using coal mine wastes as a replacement for conventional road subgrades. Various laboratory tests carried out on fresh coal mine waste collected from Barapukuria Coal Mine (Located at Dinajpur, Bangladesh) showed that, it behaves like low strength soil with 0.71% CBR and 18.74% plasticity index which is unsuitable for engineering utilization. Later, fine sand and cement were added with the waste. Three different cement proportion were tested (5%, 8% and 10% of total weight) keeping a constant sand proportion (20% of total weight). The unconfined compression strength and CBR value were found to increase greatly. Analyzing the test results, waste mixed with 8% cement and 20% sand showing 27.44% CBR and 9.09% plasticity index was found to be effective for using as subgrade. Chemical analysis of waste detected the presence of lead as 0.026 ppm which may cause groundwater contamination.

Abstract:
Leachate from coal mine waste is a serious environment problem, which has been considered as the major pollution problem associated with coal mining activities owing to high concentrations of sulfate, iron and other heavy metals. Biological treatment by sulfate reducing bacteria (SRB) has been considered as one promising alternative method for the treatment of acid leachate from coal mine waste. The treatment is based on the metabolism of SRB with organic carbon as electron donor and sulfate as electron acceptor, and the process can remove heavy metals as sulfide precipitates. In this study, ethanol was investigated as carbon source required for SRB to treat coal mine waste leachate by batch experiment. Inoculation of coal mine waste in batch reactors with SRB resulted in the efficient neutralization and high removal of sulphate (84.3%) and iron (97.2%). The result showed that the removal of sulfate and iron by inoculating coal mine waste pile with SRB could be a potential alternative to traditional treatment of coal mine waste.

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:
In this case study, metal pollution levels in mine wastes at a coal mine site in Etili coal mine (Can coal basin, NW Turkey) are evaluated using geographical information system (GIS) tools. Etili coal mine was operated since the 1980s as an open pit. Acid mine drainage is the main environmental problem around the coal mine. The main environmental contamination source is mine wastes stored around the mine site. Mine wastes were dumped over an extensive area along the riverbeds, and are now abandoned. Mine waste samples were homogenously taken at 10 locations within the sampling area of 102.33 ha. The paste pH and electrical conductivity values of mine wastes ranged from 2.87 to 4.17 and 432 to 2430 μS/cm, respectively. Maximum Al, Fe, Mn, Pb, Zn and Ni concentrations of wastes were measured as 109300, 70600, 309.86, 115.2, 38 and 5.3 mg/kg, respectively. The Al, Fe and Pb concentrations of mine wastes are higher than world surface rock average values. The geochemical analysis results from the study area were presented in the form of maps. The GIS based environmental database will serve as a reference study for our future work.

Abstract:
The article discusses the possibility of using coal waste for the preparation of mine concrete. As a result of the research, scientific and prac- tical results were obtained. It has been experimentally proved that when a small fraction of coal, which is a waste of coal mining, is added to mine concrete, the strength of concrete decreases, but with a certain ratio of this strength it is sufficient to ensure the required properties. A series of experi- ments was carried out with the addition of liquid glass to the concrete to control the setting time of the mixture. The properties of coal wastes were determined and the possibility of their use in mine concrete was investigated. It has been established that the introduction of a fine fraction of coal in the optimum quantity into the composition of mine concrete is possible without reducing technological parameters.

Abstract:
A dynamic sequencing method has been developed to simultaneously optimize the coal production rate, waste stripping rate, mining sequence, and mine life of an open-pit coal mine. The method first establishes a geological seam model of a bedded coal deposit which estimates the relevant attributes of coal seams at the center of each block on the X-Y plane. Based on the seam model, a sequence of “geologically optimum push-backs” is generated in the final pit. The geologically optimum push-backs are then put into a dynamic sequencing model and economically evaluated. The best production schedule which has the highest NPV is obtained, which indicates the best quantities of coal and waste to be mined in each year, the best zone to be mined in each year, and the best number of years to mine the entire final pit.

Abstract:
Coal mine overburden as well as thick inseam parting materials found in the lower Gondwana basin are often treated as mine wastes. Unused fly ash from coal fired plants is another waste material. This investigation focused on using these wastes to develop better composite materials. Composite materials of varying composition with coal mine wastes from 50% to 90% and fly ash from 10% to 50% were developed with 2 to 6% cement additives. Their physical, chemical and geotechnical properties were determined. OPC strongly influenced the geotechnical properties. Fly ash presence were optimized for unconfined compressive strength (UCS) and California bearing ratio for both the mine wastes. Composite materials with 70% overburden, 30% fly ash, and 6% cement showed 4.01 MPa UCS at 56 days. Similarly, 80% inseam parting, 20% fly ash, and 6% cement produced 4.90 MPa UCS at 56 days. Analysis of fly ash present in the two composites and their strength values produced linear correlations. Pearson and Spearman’s coefficients produced high correlation of −0.9 for the composite prepared with parting materials. Microstructural analysis showed C-S-H gel formation occurring at 28 days. The composites meet the strength criterion for the base and sub-base of the coal mine haul road.

Abstract:
Many countries around the world use coal as fuel for the purpose of power generation. The extraction of coal produces large volumes of waste rock (WR) that are sometimes sulphide rich (principally containing iron sulphides such as pyrite (FeS2) and pyrrhotite (Fe1-xS)), with varying quantities of trace elements such as As, Si, Cu, Zn, Ni, Co, Mo and Cr etc). Such waste is environmentally sensitive due to the risk of oxidation in presence of atmospheric oxygen and water. Sulphide oxidation may result in acidic waters (acid mine drainage, AMD), which often contains high loads of dissolved metals. Coal combustion results in large amounts of fly ash (FA), which also is of environmental concern. However, FA is alkaline and may potentially be used for neutralisation of AMD. Therefore, the AMD producing potential of WR from coal mining and the neutralisation potential of FAs from coal and biomass combustion was studied with the ultimate goal to develop a methodology to decrease the environmental problems related to these materials.WR was sampled form the Lakhra coal field in Pakistan, which has an estimated coal reserve of 1.3 Bton, from lignite to sub-bituminous in quality. The WR samples were characterised by mineralogical and geochemical methods and the acid producing potential was determined by static (Acid Base Accounting) and kinetic (modified humidity cells test) methods. Besides organic material, the WRs are composed of quartz, pyrite, kaolinite, hematite and gypsum with varying amounts of calcite, lime, malladerite, spangolite, franklinite and birnessite. The Lakhra WR has strong potential to generate AMD (-70 to -492 kg CaCO3/ton) and pollute natural waters by leaching of elements such as Cd, Co, Cr, Cu, Ni, Pb, Zn, Fe and SO42-. Three different FAs based on the origin, fuel type and storage methods were studied. They were characterised by mineralogical and geochemical methods, the leachability was studied by batch leaching tests and the potential for buffering acids and neutralisation of AMD was quantified. Fly ash from burning i) brown coal (lignite) in Pakistan (PK), ii) black (bituminous) coal from Finland (FI) and iii) biomass FA provided by a sulphate pulp and paper mill in Sweden (SE) were studied. All ashes contained quarts, PK also iron oxide, anhydrite, and magnesioferrite, FI also mullite and lime, and SE also calcite and anorthite. All ashes were enriched in As, Cd, Co, Cr, Cu, Hg, Ni, Pb and Zn compared to continental crust, and all ashes had a strong neutralisation potential, the bioash, SE, in particular. The results are encouraging and suggest that it is possible to use FA to mitigate the environmental problems with coal mine WR. Methods for that will be the focus for the continued research.

Abstract:
Low-grade coal, a poor source of energy, has long been regarded as waste material by the coal mining industry. Biological degradation of this coal material by ligninolytic fungal strains presents a viable strategy towards eliminating this unusable fossil fuel. To this end, a novel and patented bioprocess termed Fungcoal was developed. Fungcoal is a biological process utilised in the in situ treatment of waste coal and is based on the mutualistic relationship between the fungus Neosartorya fischeri and the graminaceous species Cynodon dactylon. The process facilitates the rapid conversion of waste coal into soil-like material that stimulates establishment of vegetation for eventual coal dump rehabilitation. While a number of in vitro studies have identified various fungal strains as efficient coal degraders, the mechanisms involved in the Fungcoal-stimulated degradation process have not been fully elucidated. Furthermore, implementation of Fungcoal at both pilot and commercial scale has not been achieved. Thus the objective of this work was to investigate Fungcoal as a bioprocess via examining the role of coal degrading fungi (CDF) and grasses as biocatalysts in coal biodegradation and for the self-cladding of waste coal dumps. Initially, waste coal degradation by N. fischeri, strain ECCN 84, was investigated, specifically focusing on the mechanisms underpinning the process. In vitro studies showed the addition of waste coal induced active fungal colonisation resulting in increased fungal biomass. Increased extracellular laccase (LAC) activity, occuring concomitantly with an increase in hyphal peroxisome proliferation, was also observed in the coal supplied fungal cultures. Analysis of the colonised waste coal revealed a time dependent reduction in the percentage weight of elemental carbon coupled with an increase in elemental oxygen. The results supported metabolism and degradation of waste coal by N. fischeri strain ECCN 84 and involvement of fungal extracellular laccase. The contribution of C. dactylon, a C4 grass species to in situ biodegradation of waste coal in the presence of coal degrading and mycorrhizal fungi (MF) was also investigated. Enhanced degradation of the waste coal into a humic soil-like material was observed within the rhizosphere. Analysis of the resultant substrate revealed an increased concentration of highly oxidised humic-like substances (HS). Fungi remained viable in the rhizosphere up to 47 weeks post-inoculation and cultivation of C. dactylon, indicating the resultant humic substance-rich rhizosphere provided an environment conducive for microbial proliferation and activity. Furthermore, humic substance enrichment of waste coal substrates supported germination and seedling emergence of several agronomic species including Zea mays (corn), Phaseolus vulgaris (bean), Pisum sativum (pea), and Spinacia oleracea (spinach). Use of various cladding materials to support coal biodegradation, by fungus-grass mutualism and rehabilitation of waste dumps was evaluated at commercial scale. While substantial physico-chemical changes were not evident in the absence of cladding or where waste coal was used as cladding material, successful establishment of grass cover and diversity was achieved within three hydrological cycles on dumps cladded with weathered coal. Work presented in this thesis successfully demonstrates the degradation of waste coal by N. fischeri. The biodegradation process included enhanced extracellular LAC activity coupled with increased 3 waste coal oxidation. Increased HS concentration of waste coal substrate supported germination and early seedling establishment of several agronomic species. At commercial scale a co-substrate in the form of carbon-rich weathered coal was essential to support fungus-grass mutualism and Fungcoal-induced rehabilitation. These findings support the developed Fungcoal concept and the underpinning rationale that the phyto-biodegradation of waste coal indeed depends on the mutualistic interactions between grass root exudates and the ligninolytic and mycorrhizal fungi. Taken together, these findings provide practical evidence of the contribution of fungi and grasses as mutualists in the biodegradation of waste coal and sustainable rehabilitation of waste coal dumps

Abstract:
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:
ABSTRACT Underground coal gasification (UCG) technology integrates three processes: well construction, coal mining and gasification. It not only overcomes the safety problems of existing mine coal mining, but also avoids the pollution of waste gas, waste water and waste residue in the process of surface coal gasification of traditional coal mining. It has the advantages of low gas production cost, high safety and good environmental benefits. However, effective temperature control technology of production wellbore still needs to be developed. Based on the annulus spray method and the combination of insulated oil pipe and spray device, a set of high-temperature gas spray cooling scheme is developed by using NASA variable specific heat calculation formula, considering the variation of specific heat value of main components of high-temperature mixture with temperature, and the finite element model of production wellbore is established by using commercial software (CFX), The temperature field and pressure field of production wellbore are simulated and analyzed. The analysis results show that the developed spray cooling scheme can effectively control the production wellbore temperature, achieve the design goals of slightly lower than 350 °C when the high-temperature gas is output to the ground and no gasification of annulus cooling water. The research methods and results have important practical significance for promoting the development of underground coal gasification process and even engineering application. Underground Coal Gasification (UCG) is a chemical mining method, which conducts controlled in-situ combustion and gasification of underground coal (Gregg D W and Edgar T F, 1978; Shafirovich E et al., 2009; Khan et al., 2015). A series of chemical reactions produce combustible gases such as H2, CO and CH4 (Perkins and Sahajwalla, 2006; Takyi Shadrack Adjei et al., 2023). UCG technology integrates three processes of well construction, coal mining and gasification. It belongs to a special coal mining method and is an important supplement to traditional physical coal mining technology (Lanhe Yang, 2003; Karol Kostúr et al., 2015). It replaces the huge and bulky underground coal mining equipment and ground coal gasification equipment, changes the traditional physical coal mining to chemical coal mining, realizes underground unmanned production, and avoids personal injury and mine accidents. It can not only recover coal resources abandoned in the mine, but also be used to mine thin coal seams, deep coal seams, "three lower" coal seams, and high-sulfur, high-ash, and high-gas coal seams that are difficult for underground workers to mine or are less economical and safe to mine. Moreover, dust pollution caused by coal mining and transportation is avoided, and the gasified gangue and ash remain underground (Rajesh P. Barnwal et al., 2017; Kariznovi, M et al., 2013), which reduces the environmental impact caused by the accumulation of surface solid waste, and prevents surface subsidence to a certain extent (Peng Pei et al., 2016). In a word, it overcomes the safety problems of existing mine coal mining, and also avoids the pollution of waste gas, waste water, waste residue, etc. in the surface coal gasification process of traditional coal mining, and has the advantages of low gas production cost, high safety and environmental protection. Good benefits. UCG technology is suitable for in-situ mining and transformation of difficult-to-mine coal seams, low-grade coal seams, especially deep coal seams, which improves resource utilization and drives the development of traditional industries such as coal, electric power, and chemical industry (Hossein Nourozieh et al., 2010). Therefore, UCG is a new technology of high-carbon resources and low-carbon development of clean energy, and it is also a green coal mining technology that coordinates resources and environment.

Abstract:
Diamond mining via open pit mining has been ongoing within the Tlicho region of the Northwest Territories for several decades, which includes the habitat range of the Bathurst Caribou Herd. This has led to the importance of quantitative characterization of the Zone Of Influence (ZOI), where resource development activities may be influencing the natural behaviour of the caribou herd in the tundra environment. As part of better defining and understanding the ZOI in this region, an initiative to evaluate the potential of detecting and mapping mine waste rock dust in the surrounding environment is explored. This dust has been shown to coat foliage near roads, influencing the acidity levels of the surficial soil layer and impacting the foliage distribution. To this end, field spectrometry was acquired at various distances from road ways. Satellite imagery from the Proba-1 CHRIS hyperspectral sensor and the multi-spectral Sentinel-2a system were also acquired of the region. This presentation presents the initial spectral analysis pursued to evaluate the potential to remotely spectrally detect waste rock dust material used in road construction in the surrounding tundra vegetation. Initial analysis of the Proba-1 CHRIS hyperspectral imagery shows spectral indicators of fugitive dust and waste rock easily detects the road and suggests detectable dust concentration above ambient up to a distance of under 1km from the road.
