摘要
介绍了晋城大阳煤矿综放巷道首次采用锚杆支护的设计方法、参数选择和施工质量与支护效果的现场检查与监测内容和结果。对11条巷道的检查与监测结果表明,整个试验是成功的,为沁水煤田东部边缘裂隙发育的3号煤层锚杆支护的推广与应用奠定了良好的基础。
In the paper, the design method, supporting parameters＇ selection, the local survey information of construction quality and supporting effectiveness inspecting and monitoring are introduced. The inspecting and monitoring results for 11 tunnels indicate that the experiment is successful. The good foundation of applying and generalizing bolt support in 3 # coal seam of Qinshui coal field, whose developed with fissures, is set up.
