摘要
平煤股份六矿戊_(9-10)-22180工作面外段风巷断面大,顶板为高应力小岩柱煤岩互层复合顶板,针对风巷岩层特点采用锚网索梁联合支护。介绍了锚网索梁支护的方案设计、技术关键。通过在多段巷道试验,取得了良好的效果。
The large-section outer segment of airway of V9-10—22180 working face in No. 6 Coal Mine of Pingdingshan Tian'an Coal Industry Co. , Ltd. had coal-rock alternating compound roof with high-stress rock pillar, aiming at the rock stratum characteristics of airway, bolt-mesh- cable-beam combined supporting technology was adopted, and its schematic design and key tech- nology were introduced, which achieved preferable effects in several roadway tests.
