林西矿综采工作面回撤巷道支护技术实践

Practices on Support Technology of Equipment Removing Gateway for Fully Mechanized Coal Mining Face in Linxi Mine

在林西矿综采工作面收尾时,为了对受采动影响围岩已破坏的回撤通道进行支护,基于锚杆支护原理,结合林西煤矿1081上工作面的实际情况,采用了锚杆、锚索与单体支柱配板梁联合支护技术,介绍了巷道施工方法和注意事项、锚索支护的有关技术参数以及施工的技术要求等。

At the end of the fully mechanized coal mining face in Linxi Mine, in order to support the equipment removing gateway with the mining active influenced surrounding rocks and failure, base on the bolt support principle, in combined with actual conditions of the 1081A coal mining face in Linxi Mine, the combined technology with the bolt, anchor, single prop and beam was applied to the support of the equipment removing gateway. The paper introduced the gateway construction method and the items to be noted. The paper also introduced the technical parameters related to the bolt support and the technical requirements of the construction.
