摘要
膨胀性软岩遇水强度变低、崩解、融化,这一特殊性质决定了其巷道支护方式不同于其他巷道支护形式,除了要面对高压应力问题,同时还要考虑围岩受水化影响引起的巷道变形问题。针对红庙煤矿膨胀性软岩巷道存在的难题,给出了针对性的巷道控制方案,并在实践中得到了验证,有效地控制了红庙煤矿膨胀性软岩巷道的变形和破坏。
The characteristics of disintegration, melting and reducing strength which dilatable soft rock will show after it encounter water determine that its supporting manner should be different from others because of the problems of high comprehensive stress and deformation caused by hydration. Aiming at difficulties in supporting dilatable soft rock roadway, control method was put forward to control effectively deformation and failure of dilatable soft rock roadway in Hongmiao Colliery.
