摘要
闫家沟鑫东煤矿位于内蒙古自治区鄂尔多斯市准格尔旗西部,交通较为便利,该矿井距鄂尔多斯市东胜区27km,向北200m与神~公公路相接,经神~公公路到109国道、包府公路仅15km。煤矿距包~神铁路沙圪台集装站20km左右。井田南北约长2km、,,,煤层倾角1~3°。井田工业储量为1340万吨,可采储量为1210万吨,该矿井设计生产能力为21万t/a,。
矿井工作制度为“四六”制,全矿布置一个综采工作面,工作面长度为165m。开拓方式为一对主副斜井开拓,单水平开拓全井田,主斜井采用胶带输送机运输,副斜井采用无轨胶轮车提升,采用长壁采煤法,综合机械化开采。煤流运输全部采用强力胶带输送机从井下通过主斜井到达地面工业场地,矿井辅助运输系统采用先进的无轨胶轮车运输,实现直达式辅助运输,提高了运输效率,降低了矿井综合成本,为矿井高产、高效奠定了基础。矿井采用中央集中式通风方式,抽出式通风方法,掘进面采用局扇通风。

Abstract
Yanjiagou coal mine in Inner Mongolia autonomous region east mine the ZhunGeErQi western ordos city, the traffic is convenient, this mine ordos city dongsheng area from the north, 27km 200m and god ~ male joins the highway, the road to 109 god ~ male national highway, bag mansion 15km only. From the bag ~ god coal GeTai containers of railway sand standing around 20km. Field 2km south NATO long approximately , things about km wide, km2, compartmentalized area for coal mining, coal seam thickness km average 1 ~ 3 ° Angle. Field for industrial reserves 46,657 tons, recoverable reserves for 1210 tons, the design of mine production capacity for 21 Mt/a, service of schooling for a.
Mine work system for "his" system, QuanKuang decorate a fully mechanized working face in length, face 170m. Pioneering way for a main auxiliary slope develops, single levels expanding, Lord tilt well in the field of auxiliary slope belt conveyor by transportation, trackless rubber_tyred car, the longwall mining ascension, comprehensive mechanized mining method. Coal flow transportation all adopt powerful belt conveyor by Lord from underground inclined reach the ground industrial site, mine auxiliary transportation system adopts advanced trackless rubber_tyred car transport, achieve direct type, improved subsidirary transportation and reduce the transportation efficiency for mine mine integrated cost, high yiel
