The purpose of the work is to develop recommendations for ensuring gas and fire safety when developing inclined fields of layers m42, l3, k5, hazardous for gas-dynamic phenomena. Research methods - generalization and analysis of results, methods of mathematical statistics, calculations using standard methods. As a result of the work, the technical documentation for the mining of the Krasnolimanskoye mining sites was analyzed. Recommendations have been developed to ensure gas safety when working on the sloping field of the drop-in part of the l3 reservoir and the inclined field of the m42 reservoir by highly loaded (more than 1000 tons per day) extraction areas of the Krasnolimanskoye LLC using a return air circuit, type 1-M. Recommendations have been developed to ensure the safe mining of coal seams m42 and l3, threatened by gas-dynamic phenomena, heavily loaded excavation areas with the use of a 1-M type reciprocating ventilation scheme without refreshing the outgoing air flow. Developed "Recommendations for the provision of safe working conditions when developing 5 southern lava slope No. 1 of the m42 formation of OOO Krasnolimanskoye with air velocity in the clearing excavation up to 6.0 m /". Recommendations have been developed for ensuring endogenous fire safety when working on the slope field of the m42 formation and the slope field of the drop-over part of the formation l3 in highly loaded excavation areas. As a result of the application of the developed recommendations, gas and fire safety during mining operations is ensured, which is of great socio-economic and environmental importance.
