章村矿沿空留巷围岩控制技术

Surrounding Rock Control Technology of Gob-side Entry Retaining in Zhangcun Coal Mine

摘要: 以冀中能源邢台章村矿4224采区为研究对象，通过现场调研、理论计算及数值模拟等手段，对该矿2^#煤层沿空留巷围岩稳定控制技术进行了研究，提出了无人工充填巷旁支护体的护巷方式，以补打锚索、架设单体支柱等方法作为加强支护的手段，并通过在上帮挂网的方式有效阻止了矸石流入巷道。

Abstract: 4224 mining area in Jizhong Energy Xingtai Zhangcun Coal Mine is taken as the study object, combined with site investigation, theoretical calculation and numerical simulation method, the roadway stability control technology for gob-side entry retaining in 2^#coal mine is studied. The supporting method of no artificial filling roadside support body is proposed. Supplying anchor and erecting single pillars are used as means to strengthen the support. The waste rock is effectively prevented to flow into the roadway through hanging net on upper roadway-side.
