针对mZ201工作面收尾及回撤期间受多条老巷影响,对工作面停采及收尾工作带来不利因素,通过分析工作面停采线与多条老巷的相互关系,合理确定上网停采线及设备回撤路线,降低了采面收尾及设备回撤期间的安全风险,提高工作面设备回撤效率,并有效保证了矿井的生产组织,为煤柱工作面过老巷收尾及设备回撤提供了参考方案。

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.
