摘要
结合同煤浙能麻家梁煤矿特殊的地质条件实际状况,为适应煤矿地质构造的差异并改善围岩稳定性较差的状态,对巷道顶板支护采用了"锚、网、钢带"联合支护的技术方案,结果表明该顶板设计方案可保障综采工作面掘进的安全性与稳定性。
Combined with the reality of geological conditions and i n order to adapt to the difference of geological structure in coal mine and improve the poor stability of surrounding rock,the combined support scheme of "anchor,net and steel belt"is adopted to support the roof of roadway in combination with the actual condition of special geological conditions in Majialiang Coal Mine,in order to adapt to the difference of geological structure in coal mine and to improve the state of poor stability of surrounding rock.The results show that the roof design scheme can guarantee the safety and stability of fully mechanized mining face excavation.
