摘要
赵固一矿回采巷道布置在煤层中,巷道应力高,顶底板岩性差,断面大,维护困难。对局部淋水、冒落、坍塌巷道进行了波雷因化学注浆加固试验研究。结果表明,波雷因化学注浆能够有效地加固断层破碎带,经济效益明显,为巷道支护和快速掘进赢得了宝贵的时间,具有一定的参考和推广价值。
The mining roadway of Zhaogu No. 1 Coal Mine is arranged in the coal seam, and the roadway has high stress,bad roof and floor's lithology and large cross section, so it is difficult to maintain. Through the study of poly-resin chemical grouting strengthening to the roadway with local tricking water,caving and sloughing, the results show that the poly-resin chemical grouting can strengthen fault fracture zone effectively, and this method has obvious economic benefit and earns precious time for roadway support and rapid excavation, so it has certain reference and popularization value.
