根据陈四楼煤矿工程地质条件,采用数值模拟方法研究不同开采深度、不同支护强度条件下沿空送巷围岩变形和塑性区分布规律,并分析了不同支护强度对围岩变形的控制作用,指出巷道的两帮是支护重点和难点,应当采用全长锚固锚杆支护才能满足围岩变形的要求,就深部开采回采巷道的支护提出了一些具体的技术措施。 According to the engineering geological conditions of the Chensilou Coal Mine, numerical simulation is used to study the deformation and plastic zone distribution of surrounding rock along the roadway under different supporting depths and different supporting strength. The control of surrounding rock deformation with different supporting strength is analyzed It is pointed out that the two gangways in the roadway are the key and difficult points of support. The full-length anchoring bolt support should be used to meet the requirements of the surrounding rock deformation. Some concrete technical measures are put forward for the support of the deep mining gateway.
