Methane is yet the main natural barrier for safe and efficient coal mining. This article presents data on the explosion hazard of coal mines. The need for scientific research on safe and highly productive development of gas-bearing coal deposits is substantiated. The role of preliminary drainage of coal seams to improve the safety of coal mining is assessed. The theoretical analysis results on the methods used to combat explosion hazards and the measures to enhance gas recovery in modern coal mines are described. Statistics on methane explosions in Russian mines from 1991 to 2021 are given. Conclusions are drawn regarding the inadequacy of the current methods for combating explosion hazards. To further develop explosion hazard control, it is proposed to pay attention to poorly studied phenomena. First of all, these are sudden releases of deep-earth methane from ancient pocket traps, uncontrolled electrical impulses occurring in mines and generating a spark for methane ignition, as well as possible spontaneous combustion of methane–air mixture. Therefore, new technologies are needed to combat potentially hazardous phenomena in coal mines. A proposed option for improving coal mining safety involves the implementation of automated unmanned coal mining (AUCM) technology in a space isolated from the general mine atmosphere and filled with an explosion-proof (inert) gas mixture. This technology meets the requirements of clean coal technologies, ensuring a significant reduction in carbon emissions. The proposed technology can significantly reduce the number of accidents and increase the efficiency of coal mining. The implementation of this project will be focused on a strategic scenario of maximum effect for Kuzbass mines, based on innovative and environmentally friendly technology.
