Abstract

The article analyzes the impact of endogenous fire hazard of the development of strata prone to spontaneous combustion, in particular, with the use of modern efficient equipment, on the technical and economic performance of the mine. The conclusion is made about the necessity of differentiated approach in the choice of technology for the development of mined seams. The effective technological scheme of development of strata prone to spontaneous combustion is proposed. The influence of the first layer development on the stress-strain state of the underlying layers is investigated and rational parameters of technological schemes are determined. The economic effect from the introduction of the developed technology is calculated, which is obtained by reducing the number of endogenous fires and minimizing the damage in case of their occurrence.
