摘要
在现场调研基础上,针对薛村煤矿大倾角煤层赋存特点和技术现状,确定了大倾角难采厚煤层采煤方法所应遵循的原则,在这些原则下提出了7种采煤方法的可行方案,并比较详细地分析了各自的优缺点,最后确定伪俯斜走向长壁放顶煤开采较适合该矿,为最佳开采方案。
Via locale Xuecun colliery, we forward eight doable that the optimization investigation and aim at technique actuality and the strata control around the coal face of confirm principles of inclined thick seam mining. On the base of the principles, we bring mining schemes, and compare their virtue and shortcoming particularly, lastly we choose is cross- pitch longwall oblique mining.
