近倾向断层发育的12o~25o的煤层是采用走向长壁开采还是采用倾斜长壁开采,没有一家权威机构给出定论。类似条件下甚至更大倾角的煤层采用倾斜长壁开采的回采工作面已近百个,均取得了较好的经济效益,技术可行。目前此方面的理论研究滞后于生产实践。以依兰三矿为例,利用价值工程理论方法,分析出倾斜长壁巷道布置方案的价值指数更高,经济效益巨大。从而得出结论:近倾向断层发育的12o~25o的煤层宜采用倾斜长壁开采,《煤炭工业矿井设计规范》的相关条款应予修改。
近傾嚮斷層髮育的12o~25o的煤層是採用走嚮長壁開採還是採用傾斜長壁開採,沒有一傢權威機構給齣定論。類似條件下甚至更大傾角的煤層採用傾斜長壁開採的迴採工作麵已近百箇,均取得瞭較好的經濟效益,技術可行。目前此方麵的理論研究滯後于生產實踐。以依蘭三礦為例,利用價值工程理論方法,分析齣傾斜長壁巷道佈置方案的價值指數更高,經濟效益巨大。從而得齣結論:近傾嚮斷層髮育的12o~25o的煤層宜採用傾斜長壁開採,《煤炭工業礦井設計規範》的相關條款應予脩改。

In the condition that the coal seam dip angle between 12o to 25o,as the same time, which accompanied by nearly tendency of faults development, to use of longwall mining or tilt longwall mining, there are not any one authority gives conclusion. Under similar conditions, even larger angle of coal seam using inclined longwall mining has nearly a hundred working face, and each mining face achieved good economic benefits and technical feasibility. At present domestic the aspects of theoretical research in this area lags behind the production practice. According to the actual geological condition in the third mining of Yilan, on the principle of value engineering show the value index of inclined long wall scheme is higher and proves that this scheme economic benefits is remarkable. To draw a conclusion in the coal seam dip angle of 12o to 25o accompanied by near fault dip development condition should adopt the inclined longwall downward mining and the relevant provisions of Coal Mine Industrial Design Specifications should be modified.
