摘要
锚杆支护是一种有效的巷道支户方式。文章分析了围岩与巷道支护之间的相互作用关系,提出了锚杆支护回采巷道的技术方案。通过有限元软件Midas/GTS对锚杆支护效果进行了三维模拟,分析了不同锚杆长度对于围岩稳定性的影响。
Bolting is an effective way of roadway support.The interaction relationship between surround rocks and roadway support is analyzed.The technical solution of bolting roadway is proposed.Three-dimension simulation of bolting support effects is carried out by the finite element software Midas/GTS.The influence of different bolt length on surround rocks stability is analyzed.
