针对常村煤矿强力锚杆锚索适应情况进行现场试验,观测巷道表面位移情况、锚杆锚索受力情况,试验表明巷道表面位移较小,锚杆锚索受力均能满足设计的要求。
Aiming at the adaptability of the strong anchor and anchor cable in Changcun Coal Mine, field tests were conducted to observe the displacement of the roadway surface and the stress of the anchor and anchor cables. The tests showed that the displacement of the surface of the roadway was small and the force of the anchor and cable could meet the design requirements.
