Abstracts:

The search for alternative energy sources is one of the most important tasks of our time. The main attention of research is still focused on the possibility of obtaining energy gases from coal. It is known that in underground coal extraction removed only 40-50 % of the reserves. The rest of the coal stayed underground in the form of supporting pillars. The method of controlled burning of coal pillars with evacuating to the surface of the hot products of combustion for generating electricity and heat are proposed. It is shown that the energy equation of the gas stream, which includes the change in mass of material and heat caused by chemical reactions and phase changes, adequately reflects the regularities of the interaction underground coal combustion area with the surrounding rocks and deep waters. This interaction reflects essentially influence on each other's physical and geological fields. The physical fields include: the field of reservoir pressure, temperatures, concentrations of substances and mechanical stresses. The geological fields - geofiltrational, lithological and mineralogical, structural-tectonic and others, such as a field within the stratum-block system. The established regularities of interaction of physical and geological fields makes it possible to calculate correctly the energy capacity of combustion gases and the amount of water that must be removed from the fire area. The sequence for calculating of the regimes of combustion area draining by boreholes method are given.
