【 摘 要 】

The data on gas compositions are obtained in a Kuzbass mine by the Novokuznetsk Detached Force of Militarized Mine-Rescue Unit. The analysis of 1200 mine air samples, as for instance, in Alarda mine, shows that the extreme values of fire-hazardous gas contents are (% by volume): max 0.8 for hydrogen, max 28.3 for methane, and min 0.8 for oxygen. The conclusions are drawn about possible concept of neutron-proton structure of the core being the source of hydrogen and hydrocarbon-bearing gases releasing from the subsoil of the Earth as well as about potential applicability of chemical technology for removing hydrogen from the gas mixture to increase its explosion safety.
