矿井采用一次设计、一次建成投产的移交方式2．立井开拓布置主立井和副立井两个井筒，主立井装备一对3.0t箕斗，担负矿井原煤提升任务，兼做回风井和安全出口；副立井担负矿井辅助运输任务，兼做进风井和安全出口回风大巷兼辅助运输3．贯彻了多做煤巷少做岩巷的原则，井下巷道除井底车场外均沿煤层布置，矿井移交生产时，煤巷占67.9%开采过程基本不作岩巷4．全井田只布置一个采区、一个普掘工作面，一个综掘工作面，初期移交的回采工作面布置在井田西部边界生产系统简单5．选用综采放顶煤开采，生产集中、产量较大，利于稳产、超产，材料消耗少，适应性强，效率高6．井筒工业场地布置在井田边界附近，安全煤柱与五阳矿大巷部分煤柱重叠，占压本井田少，矿井资源回收率高7、地面建筑最大限度地采用了同体联合建筑五、主要技术经济指标1．井田开拓方式：立井；2．水平划分及水平标高：全井田一个水平开采，水平标高+389.5m；3．矿井移交生产时井巷总工程量为4217.2m，其中煤巷2862m，岩巷1355.2m；煤巷占67.9%，岩巷32.1%总掘进体积为70109.58m3，其中硐室体积4827m3万吨掘进率为140.57m／万吨4．矿井工业场地工业建（构）筑物总面积：2976.4m2，总体积：17410.4m3。

胶带输送机走廊长度150.0m；5．矿井工业场地行政福利建筑（含单身宿舍）总面积1900.8m2，总体积6833.3m3；6．矿井总占地面积5.63ha（不含预留场地），其中工业场地占地面积4.43ha，排矸场地征用地1.20ha；7．矿井原煤全员效率5.48t/工；8．矿井职工在籍总人数421人；9．矿井建设总工期19.3个月，其中施工准备期2个月，建井工期17.3个月；10．矿井共迁居民136户11．矿井建设总投资9303.00万元，吨煤投资为310.10元；六、存在问题与建议1．建设单位应在主立井、副立井位置施工井筒检查孔，以便为井筒设计和施工提供可靠的依据2．请建设单位尽快与有关单位签定供电电源、共用煤柱等协议3．本井田面积甚小，为延长开采年限，建议矿方尽早考虑扩区开发方案，及早办理有关手续PrefaceOverviewEast Village Coal Mine is located in the southwestern county Xiangyuan 5km, Changzhi City area is an old Korean town of Xiangyuan County jurisdiction, under the Coal Industry Xiang five limited liability company. (Formerly East coal mine Cui) Xiangyuan County town of the ancient Han Coking Co., Ltd Huaneng. East Village Coal Mine Safety Department of the East Village part of the coal pillar, located in Lu'an Coal Industry (Group) Co. coal mine in Wuyang range Qinshui coalfield is part of the exploration area in Changzhi, mine area 3.1km2, mining coal on the 3rd The average seam thickness of 6.39m, the general inclination of less than 15 °, coal simple structure, good roof and floor lithology, geological structure is simple, spontaneous combustion of coal is not easy. Wuyang adjacent coal mines in accordance with the information relating to mining area adjacent to the mine gas emission for 3.2m3 / t. Coal mine on the 3rd with the use of reserves to 26760kt, the actual recoverable reserves 17696kt. 3 for the low-ash coal - in gray, special low - low, medium calorific value - the value of high fever Coal (SM), mainly for coking coal, power and civil coal, coking plant. Allocation of coking coal and coke is a coal shortage of the coal market, a large gap in the market, in short supply, even a few years ago to remain slack in the coal market, it is also has been a seller's market. As China's chemical industry, metallurgical industry this growing demand for coal, the coal mine on the 3rd market advantage and price advantage will be further reflected in its market has great potential.Prepared in accordance with 1.
