Today one of the main problem for areas of intense technological activities related to the production, processing and use of fossil fuels is management and environmental protection. With the current technology development difficult to achieve effective results in terms of further improving the technical and economic performance and in terms of environmental protection. Fundamentally new in the transition to underground coal gasification (UCG) and coal combustion (UCC) is the transition to non-waste technology. The possibility of smoke emission elimination through recycling. directing the underground gasification oxides of sulfur, nitrogen and other toxic components of smoke emissions. In underground water is possible their destruction to non-toxic state. Other harmful for the biosphere chemicals substances (arsenic, strontium) also remain in the underground gas generator. Also in the underground space may direct solid waste for laying out space voids possible reduction surface subsidence and preserve the landscape. Reducing the volume of drilling and laying out space allows you to transfer temporarily useless agriculture territory. Underground space of gas generators with hot rocks can be used for commercial purposes. Utilization of physical warm rocks by pumping cold and getting hot coolant can increase efficiency. But with all the above-mentioned, the environmental justification for building the station of underground coal gasification and coal combustion necessarily involves the analysis and forecast of man-made impact on the geological environment. In terms of the studied region of brawn coal Dnieper basin the prospects of widespread introduction of underground coal gasification and coal combustion technology inherent protection from problem resolution is actively used in the household groundwater from chemical contamination of underground coal combustion, disposal and coolant waste.
