摘 要:王村矿8128工作面埋藏深度为-707~-879 m,具有中等冲击地压倾向性。为解决8128工作面危险性区域的支护问题,设计在该工作面两道应用平顶形可缩性支架进行联合支护。观测结果表明:该联合支护方式可提高巷道围岩支护强度,巷道变形量在可控范围,起到巷道让压作用,确保了巷道有效的支护断面。The burial depth of the 8128 working face in Wangcun Coal Mine is-707-879 m, which has a moderate rockburst tendency. In order to solve the support problem in the dangerous area of the 8128 working face, the flat roof retractable support is designed for combined support in this face. The observation results show that the combined support method can improve the surrounding rock support strength of the roadway, the roadway deformation is in a controllable range, play the role of roadway pressure relief, and ensure the effective support section of the roadway.
