Macro test mine in Inner Mongolia Erdos Dongsheng Coalfield coppersmith River area southeast of detailed investigation, administrative divisions under the Town God Erdos Zhungeer jurisdiction.Ida from north to south 2.25km, east to west, 1.84km, area 2.3033km2, mining elevation of 1238m～1192m. Recoverable reserves of 1406.13 million tons.The designed annual output of 0.6M tons, the annual calculation of working 300 days,2000 tons daily output of raw coal. Mine Industry Square arranged in flat open areas south of the mine using inclined to open up, the return air shaft, shaft and along the coal seam roadway layout. Coal seam is divided into one panels, with a fully mechanized coal mining method of full—thickness mining. Design layout of a fully mechanized coal face and two fully mechanized excavation face.Transport by the main mine belt conveyor, auxiliary transport used rubber tire vehicle transport. Ventilation system for the parallel exhaust ventilation, heading face pressure ventilation fan for the Board—in.Keywords: macro test coal mining methods to develop transport ventilation system毕业设计说明书－ －目 录摘 要 .......................................................................................................................................IAbstract....................................................................................................................................II第一章 井田概况及地质特征 .................................................................................................11.1 井田概况 .......................................................................................................................11.1.1 位置与交通 ........................................................................................................11.1.2 地形地貌 ............................................................................................................11.1.3 水系、河流 ........................................................................................................11.1.4 气象及地震 ........................................................................................................11.1.5 矿区经济概况 ....................................................................................................21.1.6 周边煤矿 ............................................................................................................21.1.7 外部建设条件 ....................................................................................................21.2 地质特征 ........................................................................................................................31.2.1 地层 ....................................................................................................................31.2.2 构造 ....................................................................................................................41.2.3 煤层 ....................................................................................................................41.2.4 煤质 ....................................................................................................................51.2.5 水文地质 ............................................................................................................61.2.6 其他开采技术条件 ............................................................................................8第二章 井田境界及储量 .......................................................................................................102.1 井田境界 ......................................................................................................................102.2 井田地质储量及工业储量 ..........................................................................................102.2.1 地质储量 ..........................................................................................................102.2.2 工业储量 ..........................................................................................................102.3 井田可采储量 ..............................................................................................................11第三章 矿井工作制度、设计生产能力及服务年限 ...........................................................133.1 矿井工作制度 ..............................................................................................................133.2 矿井设计生产能力及服务年限 ..................................................................................13第四章 井田开拓 .....................................................................。
