摘　　要：通过理论计算,确定上部煤层开采对底板的破坏没有延伸到下部12#煤层顶板,在破坏区不会影响锚索锚固体岩层稳定的基础上,给出合理的锚杆锚索支护参数,支护方案的数值模拟表明,巷道围岩位移量较小,支护效果显著。Determined by theoretical calculation,the upper coal seam mining damage to the floor did not extend to the lower 12#coal seam roof,on the basis of the damaged area will not affect the stability of anchoring rock,given reasonable bolting and cable anchor support parameters,through numerical simulation of support schemes,tunnel surrounding rock displacement is small and supporting effective.
