“…It should be noted that potash stratum III, which lies above, is hazardous in terms of gas-dynamic phenomena. From the practice of mining, it is known that gasdynamic hazard increases with the depth of mining as the rock pressure increases [7][8][9][10][11][12]. In this regard, the study of the gas content of rocks in potash stratum IV is of not only scientific, but also practical interest.…”
