Abstract
In view of the fact that the mZ201 working face is affected by multiple old roadways during the ending and withdrawal period,which brings unfavorable factors to the stop mining and ending work of the working face,the interrelation between the stop mining line of the working face and multiple old roadways is analyzed,and the online stop mining line and equipment withdrawal route are reasonably determined,reducing the safety risks during the ending and equipment withdrawal period of the mining face,improving the efficiency of equipment withdrawal in the working face,and effectively ensuring the production organization of the mine,which provides a reference scheme for the ending and equipment withdrawal of the coal pillar working face passes through the old roadway.关键词
