FIELD: mining.
SUBSTANCE: proposed method consists in measurement of coal seam methane content, definition of block methane-bearing capacity, registration of methane flashes and blasts during operation and revealing of frequency of methane dangerous situations. Note here that blocks are isolated at mine fields with different mining conditions while methane-bearing capacity of said blocks is defined by methane content of volumes of free methane release to set the explosion hazard index. Note here that said index is set by most dangerous methane-bearing capacity blocks with due allowance for methane release volumes from accumulation sources.
EFFECT: higher validity of evaluation.
