摘要
以成庄矿回采面53151巷地质条件为工程背景,拟定采用小煤柱沿空掘巷技术,现场留设6.0 m煤柱;采用“深孔预爆破卸压+锚网索补强支护+滞后注浆加固”多重支护手段;矿压监测数据表明,该巷道围岩处于稳定状态,支护措施合理有效。
The paper introduces the application of small-pillar gob-side entry driving technology with multiple support method of pressure relief by deep-hole pre-splitting blasting,reinforcement bolt-mesh-cable support and delayed grouting reinforcement at53151 Lane of mining face in Chengzhuang Colliery.The mine pressure monitoring data show the support measures are reasonable and effective with stable surrounding rock.
