摘要
阳泉煤业集团有限公司二矿81007回风顺槽掘进面受采空侧动压影响,通过对比分析锚网支护两种不同支护参数的支护效果,试验验证巷道的合理支护参数,优化改进施工工艺。实践证明,高预应力锚杆(索)强力支护可有效控制围岩变形与破坏,效果显著。
By analyzing and comparing the supporting effect of two different support parameters of anchor net support,the reasonable supporting parameters of the goaf side dynamic pressure roadway in thick seam are verified by experiments,the construction technology is optimized and improved in 81007 heading face in No.2 Colliery,Yangquan Coal Industry Group Co.,Ltd..Practice proves that high prestressed anchor(cable) support can effectively control the deformation and failure of surrounding rock and the effect is significant.
