摘　　要：针对下石节煤矿2-#副斜井断层区围岩松散破碎,受水影响较大的特点,从加固破碎岩体和提高支护阻力两方面出发,提出了二次高强锚网索＋U型钢支架＋围岩注浆高强稳定型协同支护技术。现场试验表明此支护技术方案有效解决了该巷道变形难题。According to the characteristics of broken and loose surrounding rock and influenced by water in faults zone of 2-#auxiliary inclined shaft in Xiashijie Mine,Based on the consideration of reinforcing broken rock and increasing support resistance,the combined support technology of secondary high-strength anchor-mesh-cable ＋ U-shaped steel support ＋ surrounding rock grouting is proposed. Field test shows that the support program can solve the problem of the deformation of surrounding rock.
