摘要
为研究准东煤田巨厚煤层分层综放开采首分层顶煤冒放性问题,利用相似模拟、数值模拟和理论分析对B1煤层首分层综放开采进行分析,认为B1煤层首分层顶煤冒放性较好,推进至距切眼36～40 m,顶煤基本可以随采随冒。
In order to study the problem of east junggar coalfield extremely thick coal seam layered caving first top coal caving stratified,using similar simulation,numerical simulation and theoretical analysis on the B1 coal caving first stratified analysis,considering that B1 seam top coal caving first stratification was better. Advancing 36 ～ 40 m from cut,basic top coal can be caving with mining.
