摘要
总结了平煤股份六矿以往穿煤层施工架棚支护存在的弊端,决定在戊9-10-22160机巷联络巷采用锚网索联合支护方式进行穿煤层联络巷的施工。介绍了根据联络巷穿过煤岩体的特性合理选择支护方案和确定锚网索支护参数的方法。方案经实践证明取得了良好的效果。
After summarizing the drawbacks of shed support constructed through the coal seams in No. 6 Mine of Pingdingshan Tian＇an Coal Co.,Ltd.,the paper decides to apply the boltmeshanchor joint support method to construct the tunnels through coal seams in the construction of E9-10-22160 machinery and connection tunnels. It introduces how to select reasonably the support scheme and determine the boltmeshanchor support parameters according to the characteristics of coal rock the connection tunnels pass through. The scheme is proved by practice to have achieved good effectiveness.
