摘要
结合兴源矿实际情况,对6号煤层6410工作面采用条带式开采,为防止工作面突水,利用固支梁力学模型计算岩梁极限垮距及各岩层断裂时的临界开采长度,确定条带开采时采宽和留宽,最终确定条带开采方案。
Combined with actual situation of Xingyuan Mine, No. 6 coal seam 6410 working face was adopted strip mining,in order to prevent water burst in working face, mechanical model of solid supported beam was used to calculate ultimate collapse distance of rock beam and critical mining length in fracturation, the mining width and width left in strip mining were settled and the strip mining plan was chosen.
