摘要
以覆岩破坏规律现场实测为依据,应用比值判别法、三带判别法对福城煤矿59、煤层上行开采的可行性进行了理论研究,5、9层煤上行开采安全、合理,结论对于现场生产具有重要的指导意义。
According to overburden failure law of field measurement, apply ratio discriminatory,three zone discriminance to research the feasibility of five and nine coal ascending mining in Fucheng mine, five and nine coal ascending mining safety and reasonability, the conclusions have important guiding sig- nificance to field production.
