1、内蒙古科技大学内蒙古科技大学 本科生毕业设计（论文）本科生毕业设计（论文）题题 目：宝丰煤矿目：宝丰煤矿 6-2 中号煤层开采设计中号煤层开采设计姓姓 名：李彦鹏名：李彦鹏学学 号：号：专专 业：采矿工程业：采矿工程班班 级：采矿级：采矿 10-3 班班指导教师：吴国良指导教师：吴国良 郑文翔郑文翔I摘摘 要要本次毕业设计的题目是宝丰煤矿 6-2 中号煤层的开采设计，该矿位于鄂尔多斯高原东部，井田面积为 4.089km2，煤层平均厚度为 2.15m，倾角 13 度，属于近水平煤层。该矿的地质储量为 1178.05 万吨，可采储量为 991.49 万吨，设计年产量为 60 万吨，矿井的服务年限为
2、 12 年。在该矿井的西南方向布置工业场地，采用斜井单水平开拓方式，并设置主斜井、副斜井和专用的回风斜井来负责运输及通风。井下主运输系统采用胶带运输机运输，辅助运输采用轨道运输机运输。对于该矿选用单一长壁走向采煤法，井田内共划分七个带区，由南向北依次开采，采用综合机械化采煤工艺，设置一个回采工作面，一个掘进工作面。采空区采用全部垮落法来处理，本矿采用抽出式的通风方式，中央并列式的通风系统，掘进工作面采用局部通风机通风，整个系统满足该矿井的生产需求。关键词：关键词：斜井开拓，单一走向长壁采煤法，综合机械化采煤，抽出式。IIAbstractThe topic of this graduation
