摘要
同煤集团四台矿二水平-550进风石门巷道的地质条件比较复杂,因为埋藏深,地应力大,巷道所处围岩破碎,加大了其施工和支护难度。针对以上问题,技术部门根据新奥法和局部欠支护理论,对高应力软岩巷道的施工和支护进行了技术尝试。实践结果表明该支护技术有效,可以保障掘进工作的正常进行。
The geological conditions of the two level-550 intake air crossdrift roadway in Sitai Mine, Datong Coal Mine Group is quite complicated, with its coal buried deeply, undertaking very high underground pressure. As a result, its surrounding rock is broken into pieces, increasing the difficulty for its construction and supporting. In view of the above problems, the technical department has made a new technological attempt on the construction and supporting work of the high stress soft rock roadway according to the theory of new Austrian law and local under-support theory. The practical results show that the support technique is effective and can guarantee the normal operation of coal mining.
