文档介绍：摘要
本设计为内蒙古特弘煤炭集团有限责任公司来叶沟煤矿6—2号煤层年产60万吨地下开采设计。内蒙古特弘煤炭集团有限责任公司来叶沟煤矿位于内蒙古自治区鄂尔多斯市准格尔旗纳日松镇宏景塔村(原乌日高勒乡)境内。
井田为一不规则的多边形,,,。开采标高:1238m~。
本设计年产量为60万吨,按年工作日300天计算,日产原煤2000吨。工业广场布置在井田南部地势平坦的开阔地,矿井采用斜井开拓,沿煤层走向布置井筒和大巷。煤层共分1个盘区,采用一次采全厚综采放顶煤采煤方法开采。设计布置1个综采工作面和1个综掘工作面。
矿井主运输采用胶带机运输,辅助运输采用无轨胶轮车运输。通风系统为中央并列抽出式通风,掘进工作面通风方法为局扇压入式。
关键词:来叶沟煤矿开拓系统采煤方法运输通风系统
Abstract
The macro is designed to measure annual coal mine million tons 6—2 preliminary design of underground mining. 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 , east to west, , area , mining elevation of 1238m~1192m. Recoverable reserves of million tons.
The designed annual output of 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
