FIELD: mining.
SUBSTANCE: method to reduce gas abundance and dustiness of production units in mines, includes installation of degassing pipes and exhaust of gas into degassing gas line and cutting slots in bottomhole massif by methods of hydraulic cutting. Hydraulic cutting of slots is carried out for excavation of mineral in blocks, which are then transported by section transport to grinding chamber, in which mineral blocks arriving from mining face are destroyed. Besides, grinding chamber is arranged outside the limits of fresh air jet arriving to air mining face, and gas is exhausted into degassing gas line from grinding chamber, by means of installation of degassing pipes in specified chamber.
EFFECT: lower gas abundance and dustiness at production units in mines.
