摘要
Abstract
There are many old roadways inside the 93lower21 working face of Nantun Coal Mine.In order to ensure the safe and smooth passage of the working face through old roadways during the stoping period,the old roadways in the same layer are reinforced by using ways of filling and construction anchor net cables before stoping.The underlying section of the through layer old roadways is treated by adopting method of construction wood crib,and the underlying old roadways are treated by using filling method.During the stoping period,the use of pre-braking knives and rapid advancement can ensure the safe and smooth passage of the working face through the same layer old roadways;A method of"exploration → filling → verification → re-filling and re-verification"is created for passing through the underlying old roadway,by applying this method,the safe and smooth passage of the working face through the same layer old roadways can be ensured.关键词
