摘要
Abstract
Through gas emission parameters testing and characteristics analyzing of North wing belt roadway fully mechanized excavation face in Sihe coal mine 2301s working face,it is obtained that the relationship between gas desorption intensity of fallen coal and exposure time in North wing belt roadway of 2301s working face is approximately hyperbolic.Mathematical model of coal wall gas emission per in unit time at heading face is estabilished,which provides a basis for studying gas emission law of the 2301s face in Sihe coal mine关键词
