Research on the Severity Assessment of Coal and Gas Outburst
Coal and gas outburst is one kind of dynamic force phenomenon having noise and fierce force, which can destruct underground facilities, destroy the ventilation system, and the underground roadway are full of gas and coal dust, personnel are suffocated, coal stream are buried, so far as to fire and gas explosion accident., therefore accurate forecast coal and gas outburst severity is especially important. In this paper, some important induces that influenced coal and gas outburst were analyzed, and coal and gas outburst severity model was established, multidimensional grey evaluation was applied to analyze the consequence of coal and gas outburst, then mining danger classes was determined, thereby the severity of coal and gas outburst was appraised.
