阳煤三矿成功上行开采研究

Successful Uplink Mining Mechanism of No.3 Coal Mine

阳泉矿区位于沁水煤田北部,主采15号煤层,阳煤三矿位于阳泉矿区本部。利用比值判别法、"三带"判别法等方法对综采放顶煤上行开采进行可行性分析,得出了在阳泉矿区所在煤田范围采用上行开采技术可行,安全可靠,并能取得良好的经济效益,为阳煤集团上行开采提供了可靠的理论依据。

Yangquan Mining Area is located in the north of Qinshui coalfield, the main mining No. 15 coal seam, Yangquan Mining Area is located in yangquan mining area, using the ratio method, the method such as ＂three zones＂ criterion of ascending mining feasibility analysis of fully mechanized caving coal face, the range in yangquan mining area coal field is obtained by ascending mining is technically feasible, safe and reliable, and it can obtain good economic benefit, for ascending mining Yangquan Coal Mine Group provides the reliable theory basis.
