在分析了煤层地质条件的基础上,讨论了适合9号煤层的3种采煤方法,通过分析分层开采、大采高综采和综采放顶煤开采的优缺点及适应条件,确定了9号煤层采用综采放顶煤采煤方法,并结合沙基岩浅埋深煤层的矿压规律,探讨了回采工艺参数。开采实践证明采煤方法及工艺参数的选择较合理,开采效果较好,给准格尔矿区东部厚煤层开采提供了借鉴的经验。 Based on the analysis of geological conditions of coal seam, three kinds of coal mining methods suitable for No.9 coal seam are discussed. By analyzing the advantages and disadvantages of stratified mining, fully mechanized longwall coal mining and fully mechanized top coal caving mining, In the No.9 coal seam, the fully mechanized top coal caving method is adopted. Combined with the rock pressure law of shallow burial deep coal seam, the technical parameters of mining are discussed. Mining practice has proved that the choice of coal mining method and process parameters is reasonable and the mining effect is good, which provides experiences for mining thick coal seam in eastern Jungar Mining Area.
