摘要
论述了急倾斜中厚－厚煤层水平分段巷道放顶煤采煤方法，分析了工作面生产能力和促使顶煤冒落放出的措施。工业性试验表明，这是拓宽放顶煤采煤法在急倾斜煤层应用的有效途径。
This article discusses caving method in steep medium-thickness and high seam of horizontal sublever roadway analyses the face productivity and the measures to improve the falling and giving out of roof coal. The industrial experiment shous that this is the most efficient way of developing caving method in steep medium-thickness and high seam.
