1、内蒙古科技大学毕业设计说明书XXXXXXXX本科生毕业设计说明书题目:闫家沟鑫东煤矿4煤层年产21万吨开采设计学生姓名:XXX学号:XXXX专业:采矿工程班级:XXX指导教师:XXXX6--内蒙古科技大学毕业设计说明书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、东西宽约为7.5km左右,井田面积为9.4369km2,开采煤层平均厚度2.35m,煤层倾角1~
2、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,服务年限为41.2a。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
