摘要
介绍了红柳林煤矿二号进风斜井在陕北毛乌素沙漠边缘特殊表土地层条件下的施工情况,通过优化施工装备、改进施工工艺,解决了特厚砂层、含水砂砾粘土层长距离砌碹、加固等一系列难题,对类似地层条件下的矿井建设具有一定的借鉴意义。
Based on the analysis of the special topsoil condition of the edge of the Maowusu Desert in northern Shaanxi and the construction condition of No. 2 air inclined shaft in Hongliulin coal mine,the construction equipments and improving construction technology were optimized,the problems of long-distance reinforcement and arching support for extra thick sand layer and aquiferous gravel clay layer were solved. The results provide some reference significance for the mine construction in similar geological conditions.
