| 摘 要： | 由于交岔点支护跨度大、顶板应力增高、支护单一,交岔点支护服务时间相对较短,且修复频繁,长期以来,巷道交岔点支护一直是困扰煤矿支护的难点。郑煤集团裴沟煤矿对巷道交岔点采用架异型U型钢支架、帮部工字钢耦合、喷浆封闭、打锚索、索钢耦合、注浆充填的联合支护技术,提高了巷道交岔点的支护强度及稳定性。

| Abstract: | For a long time,roadway intersection supporting has been the difficulties plagued coal mines supporting,because span of intersections supporting is large,roof stress is concentrated,supporting way is single,service time of roadway supporting is short,so frequent repairs are needed on intersection supporting.Combined supporting technology,which uses U shaped steel supports,combined supporting of side i beam,sealing with shotcreting,anchor cable construction,combined supporting of anchor cable and i beam,grou... |
