摘　　要：为了解决1307巨厚煤层工作面顺槽变形严重的问题,文中采用数值模拟的方法,设计了3种顺槽支护方案,并对各方案进行模拟,结合巷道控制效果及经济投入,最终确定了方案3(3根长锚索+2根短锚索)为最优支护方案。经过对巷道支护效果的考察,确定新型支护方式能够对巷道围岩得到有效控制。in order to solve the huge thick coal seam working face 1307 gateway deformation serious problem,this paper adopts the method of numerical simulation,the design of the three kinds of gateway support scheme,and used for simulating the scheme,and combined with the control effect of roadway and economic investment,ultimately determines the scheme 3(three long anchor cable+two short anchor cable)for the optimal supporting scheme.Effect of roadway support,determined new supporting method can effectively control of surrounding rock of roadway.
