摘要
针对大同煤矿集团公司同忻矿特厚煤层综放工作面开采过程中出现的临空顺槽变形破坏严重、难以维护的现状,对2100顺槽变形破坏原因进行了详尽分析,据此提出了针对性的控制措施。
According to the situation that the fully mechanized working face with extra-thick coal seam in Tongxin mine of Datong Coal Mine Group causes airport crossheading roadway serious destruction and difficult maintenance when mined, the causes of 2100 crossheading roadway deformation and destruction is analyzed particularly, and specific control measures are proposed.
