摘要
分析了异面近距离斜交巷道下位巷道顶板的破坏形式及造成破坏的原因,论证了采用锚杆(索)支护技术对此类巷道支护的可靠性,并介绍了义安煤矿应用的成功实例,对同类巷道的施工具有较好的借鉴作用。
reak forms and break reasons of top plate of tunnel beneath another tunnel with short distance are analyzed. The reliability of using rock bolting technique to support such tunnel is discussed. The experience of successful application of rock bolting technique in Yian Coal Mine can be taken for reference by similar mines.
