摘要
结合三交河煤矿2#煤层合并区域的生产地质条件,通过建立经济效益比较模型,从技术、经济效益2个方面进行深入分析,得出结论:大采高综采方法能够有效提高矿井规模和经济效益,为厚煤层安全高效回采方法的选择提供借鉴。
Combining with production geological conditions of merger zone of 2# Coal Seam in Sanjiaohe Coal Mine,through the establishment of economy comparison mode,a deep analysis on mining method from the aspects of technical and economic benefits was made.The conclusion was drawn that the large mining height fully-mechanized method can effectively improve the scale and economic benefit of the mine,which can provide reference for the choice of safe and efficient mining method of thick coal seam.
