摘要
本文介绍了在晋城矿务局凤凰山矿和淮南矿务局一矿煤巷进行锚拉支架现场试验研究的部分结果。在凤凰山矿 3 #煤上风巷进行了 2 0 0 m锚拉支架试验 ,在谢一矿进行了 2 45 m锚拉支架试验。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。
This paper is a part of experimental study achievement that Li Xianwei team gained it on site of Jincheng bureau and Huainan bureau. It is measured anchoring force of bolt, pulling force of pull rod, upward force of pull rod, the surface displacement of tunnel, the inside displacement of tunnel. The achievement is fundamental data to study supporting effect by truss.
