综采工作面极近距离跨空巷回采技术
Extreme Distance Crossing Abandoned Roadway Mining Technology of Fully Mechanized Mining Face
摘要
Abstract
To guarantee the safety mining of 18201 working face,numerical simulation is used to analyze the support parameters of wooden stamp support.Through the formula,the depth of coal seam floor damage and the floor stability of working face during mining period is calculated,which guarantees the safety mining of work face in theory.The mine pressure monitoring results show that the damage of surrounding rock does not appear and the support parameters of wooden stamp are reasonable in the caving mining face passing through the abandoned gateway.关键词
