摘要
本文针对磁窑沟煤矿11102综采工作面回撤期间运输巷发生冒顶事故,根据现场实测对近距离煤层工作面回采巷道冒顶机理进行了分析研究,并制定了治理措施。通过对冒顶区域进行注浆加固,将被埋设备及时清出,并确保了工作面的顺利回撤,极大的减少了事故造成的经济损失。
Because the roofing accident occurred in the transportation roadway during the withdrawal of 11102 fully mechanized coal mining face in Ciyaogou Coal Mine,this paper analyzed and researched the roofing mechanism of the mining roadway in the close-up coal seam working face based on on-site measurement,and formulated the control mea⁃sures.By grouting and strengthening the roof falling area,the buried equipment is cleared in time,which ensures the smooth withdrawal of the working face and greatly reduces the economic loss caused by the accident.
