摘要
简要分析了煤矿回采工作面掘进过程中巷道出现破坏的原因,结合巷道支护具体案例,提出"锚杆+金属网+锚索"、"单柱液压支架+钢梁"的联合高强支护方案。实践检验发现本支护方案能够达到预期的效果,对于保障井下安全具有重要的理论意义和实践意义。
This paper briefly analyzes the reasons for the damage of the roadway during the excavation of the coal mining face. Combined with the specific cases of roadway support, the combined high-strength support of "anchor+ metal mesh + anchor cable", "single column hydraulic support + steel beam" program is proposed. Practice tests have found that this support scheme can achieve the expected results, which has important theoretical and practical significance for ensuring underground safety.
