摘要
针对东滩煤矿3304工作面回采巷道锚网带、锚索联合支护成本高、密度设计不合理以及回采巷道掘进速率较慢的问题,有针对性的对支护参数进行重新设计与计算,确定了新的支护参数,并结合数值模拟与现场工业性试验进行研究。研究结果表明:在适当调整锚网索支护参数后,支护成本较原支护降低了18%,而回采巷道的掘进速率得到明显提升,巷道围岩变形得到有效控制,确定了支护参数的合理性、经济性以及安全性。
Based on high support cost of anchor mesh belt, anchor cable joint, unreasonable design density and low mining rate of recovery roadway in 3304 working face of Dongtan Mine, support parameters were correspondingly re- designed and calculated, the new support parameters were made, combined with numerical simulation and field industrial test, the result showed that the reasonable anchor net supporting parameters reduced 18% support cost, with obvious mining rate advancement, good control of roadway deformation, the reasonability, economy and safety of support parameters were made.
