辛置矿10-430B采面区段平巷破碎段控制与治理实践

Control and treatment practice of crushing section of entry in 10-430b mining face section of xinzhi mine

为解决辛置煤矿东四采区10-430B采面运输平巷过断层群围岩破碎、大变形破坏难题,以矿山岩体力学和围岩耦合支护理论作为指导,在对采面地质条件分析基础上,通关“预注浆+锚网+锚索”多种联合支护方案,在平巷内形成多层结构体系,不仅提高了围岩自身承载性,还较好的减少了巷道大变形以及返修工程量。

to solve the symplectic buy 10-430-b on grabbing the mining area of coal mine haulage roadway through fault group of crushing,large deformation of surrounding rock damage with mining rock mass mechanics and rock mass coupling support theory as the guidance,based on the analysis of geological conditions of the mining surface,customs clearance"pre grouting,anchor net and anchor cable"a variety of combination supporting scheme,in the entry form a multilayer structure system,not only improved the surrounding rock self-bearing sex,also better to reduce the large deformation of roadway and the repair of quantities.
