摘要
协庄煤矿3417W工作面是大采深采场,通过采用数值模拟方法,确定在采用不同锚杆支护设计方案条件下的巷道破坏、应力分布和锚杆受力情况以及巷道表面位移的大小,为类似条件下的煤层开采和巷道支护提供了理论依据。
3417W is a deep stope of Xiezhuang Coalmine with complicated mining conditions. There are different alternatives of rock bolting for the stope. Using data simulation method and under conditions of different support alternatives, the heading damage, stress distribution, force bearing of bolts and surface displacement extent of heading are analyzed. The result of analysis can be taken as theoretical basis for coal mining and heading support of coalmines with similar geological conditions.
