1、同煤集团煤峪口矿同煤集团煤峪口矿 3 3 煤层初步设计煤层初步设计本科毕业论文本科毕业论文(设计设计)题目：同煤集团煤峪口矿 3#煤层开采初步设计学院：煤炭工程学院班级：09 采矿工程一班姓名：贾少华指导教师：王星亮职称：副教授完成日期：2020年6月5日同煤集团煤峪口矿同煤集团煤峪口矿 3#3#煤层初步设计煤层初步设计摘要本次设计是开采煤峪口煤矿 3 号煤层，设计图纸共五张，说明书共十章。煤峪口煤矿位于大同市南西65，直线距离14公里。其地理位置为北纬40158.37，东经 113738.28。区内交通十分方便，可通向全国各地。本矿井设计要紧是开采 3 号煤层，该煤层结构简单、埋藏稳固。在本
2、井田范畴内，煤层平均厚度为 5.02 米，最薄 4.6 米，最厚 6.4m，井田均可采。本井田划分为二个盘区，回采工艺采纳后退式、一次采全高的采煤方法，采纳“四六制”作业制度。工作面的设备有双端可调双滚筒采煤机、滑移支架、可弯曲刮板运输机、破裂机、转载机等。顶板治理采纳滑移支架，采空区采纳全部跨落法治理顶板。矿井运输大巷采纳皮带运输作为主运输，采纳连续运输车作为辅助运输，矿井通风采纳轴流式扇风机边界、抽出式通风方式。在设计过程中表达了大型现代化矿井高产高效的设计原则，采纳系统优化的方法，使矿井能够在一矿一井一面的条件下达到最佳生产能力。矿井采纳三条煤巷，实现了集中生产；采纳大功率、高效能的采煤
3、机和大运量、高寿命的刮板输送机，提高了设备的配套能力及可靠性，保证工作面高产高效；副井采纳罐笼提升，主井采纳斜井皮带运输。在设计说明书中完整地阐述了本设计各生产系统的选择和设备的配置情形，并在重要的、关键的方案作了技术比较，这是一个进展的矿井。因此在整个设计过程中表达了现代化的特点。关键字：立井；高产高效；倾向长壁采煤方法；现代化；一次采全高ABSTRACTThis design is to mine Meiyukou to turn the coal mine No.3 coal seam,thedesign diagram paper is total 5,and the manual i
