摘要
本课题组先后在晋城矿务局凤凰山矿和淮南矿务局谢一矿煤巷进行了锚拉支架现场工程试验研究工作。现场实测了锚杆的托锚力、拉杆的拉力、拉杆上托力、巷道表面位移、围岩深部位移等参数,为锚拉支架的现场应用和机理研究提供了必要的现场资料。
This paper is a part of experimental study achievement gained on mine sites of Jincheng bureau and Huainan bureau. Anchoring force of bolt,pulling force of pull rod,upward force of pull rod,the surface displacement of tunnel,and the displacement in the depth of surrounding rocks were measured. The data are necessary for the study on supporting effect by truss.
