PHYSICAL PRINCIPLES AND MATHEMATICAL DESCRIPTION OF THE FORMATION OF AIR VELOCITY FIELDS AND CONCENTRATIONS OF GAS IMPURITIES IN MINING WORKINGS OF COAL MINES

News of the Tula state university. Sciences of Earth, 2023
The air composition of the mine atmosphere in coal mines; Safety Rules regulate heat-humidity and speed conditions created by the ventilation system. At the same time, physic-chemical, aero-gas-dynamic and thermos-physical processes occur, which affect ...
