摘要: 摘 要:膨胀性软岩倾斜煤层回采巷道的支护历来十分困难,采用传统的支护形式很难控制住巷道围岩的变形。本文结合鹤壁十矿1202中工作面的工程实例,分析了倾斜煤层膨胀性软岩回采巷道的破坏原因,并有针对性的提出了锚网索钢带耦合支护技术,并在工程中得到了验证。同时分析了其在类似巷道支护中的可适用性。
关键词: 倾斜煤层回采巷道, 非对称, 耦合支护
Abstract: Abstract:It is all kown that the support of inclined coal seam gateway with expansile soft rock has always been very difficult,it is very hard to control the deformation of surrounding rock under traditional support forms. Based on the engineering of 1202 mining face at the tenth coal mine of Hebi,this article analyses the destruction reasons of inclined coal seam gateway with expansile soft rock and puts forward bolt-mesh-cable-belt coupling support technology,this technology has been verified in the engineering. It also analyzes its applicability in the similar roadway.
Key words: Key words:inclined coal seam gateway, asymmetric, coupling support
