摘要
谢桥煤矿主采的13-1煤层为典型的"三软"煤层,尤其是经过复杂地质构造带时,工作面及端头管理困难。采取新型高分子聚合材料(马丽散)注浆加固工艺结合工作面煤壁打聚氨酯木锚杆加固工艺综合治理煤壁、顶煤,进而达到控制顶板及煤壁的目的,取得了显著的安全效益和经济效益,同时为在相似条件的综采和大采高工作面开采中推广、应用提供一定的借鉴作用。
13 - 1 coal seam is the typical three-soft coal seam which is the main mining seam in Xieqiao coal mine. It is harder to operate while passing complex geological structures. Control apical plate and coal wall with the method of injecting malisan which is a new polymer polymerized material grouting strengthening technology combining polyurethane wood anchor strengthening technology. This method is a reference for fully mechanized and large cutting height workface mining under the same conditions.
