FIELD: mining.
SUBSTANCE: method includes excavation of a material from a bottomhole of an underground mine, using a continuous shearer or a longwall shearer, to develop an empty space and a mined space, supply of a foaming composition into an empty space and into a mined space and reduction of methane content measured in a tailgate at least by 0.1 wt %. Supply of the foaming composition into the empty space and into the mined space is carried out from one of the following: a machine for sight pillars excavation, a part of a continuous shearer, a part of a longwall shearer and a part of a machine for sight pillars excavation.
EFFECT: higher efficiency of mining minerals with excavation of sight pillars, mining in short and long walls.
