急倾斜中厚-厚煤层巷道放顶煤采煤法
Roadway Caving Method in Steep Medium thickness and High Seam
【摘要】 针对急倾斜中厚-厚煤层的力学特性,提出“巷道”放顶煤工艺,在梅田六矿工业性试验成功,取得了单产、工效、回采率高;掘进率、含矸率、材料消耗、劳动强度、生产成本低;实现了全风压通风、安全条件好的效果。为急倾斜中厚-厚煤层的开采找到了一条切实有效的途径
【Abstract】 Considering the mechanical property of the steep mdium thickness and high seam,the author presents the method of “roadway”caving which has been employed in an industrial experiment in the 6th Meitaian mine, and obtained the good result, i e, unit output、 working efficiency and recovery rate are high; drivage ratio、 refuse rate、 material consumption、 labour intensity and lost of production are low, ventilation and safety is fine Practically, this method can be regarded as a good and efficient way to mine steep medium thickness and high seam
