设计题目: 大湾煤矿中井2,11号煤层开采设计 专 业： 本 科 生： （签名）___________ 指导老师： （签名）___________ 摘 要 本设计所做为大湾煤矿中井2,11号煤层，井田面积10.85km2，全井田内煤层资源总量8235.5万t，设计可采储量5498.8万t，设计生产能力90万t/a，服务年限44a。 本矿井采用斜井单水平开拓。设置三个井筒，即主斜井、副斜井及回风斜井。水平标高为+1360m，盘区划分，主斜井采用胶带输送机运输，副斜井采用矿车辅助运输，工作面长度160m，工作制为“三八制”，日进5刀煤，采用一次采全高走向长壁综合机械化采煤法。本矿井田面不大，为高瓦斯矿井，采用中央并列式通风系统，抽出式通风方式。 关 键 词：斜井单水平开拓 一次采全高 高瓦斯 中央并列式通风 设计类型：模拟型 Subject: dawan coal mine mining design Professional: Mining Engineering Undergraduate:YuanChun ( signature ) ___________ Teacher: ZengYouFu ( signature ) ___________ Abstract The job is to design the 2th and11th coal seam of dawan Village Coal Mine. Ida area is 10.85km2.Coal geological conditions of the sixth coal seam of the mine are simple. The whole Ida seam resources amount to 82.355million tons and the design of recoverable reserves is 54.988 million tons.The design production capacity is900,000 t / a and the service life is 44a. The mine uses the inclined single-level open up and sets three wellbore inclined, vice inclined and return air inclined. The level elevation is +1360m as follows disk zoning, strip mining. The main inclined well uses belt conveyor transport and the vice inclined well uses winch auxiliary transport. The face length is160m as follows the 3-8 work system into five cycles each day. The mine uses the longwall mining overall high towards mechanized mining method. The area of this high-gas coal mine is small as follows the parallel central ventilation system and the exhaust ventilation methods. Key words: Inclined to develop a single standard Mining overall height High gas Central tied for ventilation Design type: simulation model 目录 第一章 地质概况矿（井）田 1 1.1矿井位置及交通 1 1.1.1、交通位置 1 1.1.2 地形地貌 1 1.1.3 气象及水文情况 2 1.1.4 矿井概况 2 1.2矿井田地层及地质构造 4 1.2.1地层 4 1.2.2构造 6 1.3矿体赋存特征及开采技术条件 9 1.3.1煤层及煤质 9 1.3.2 瓦斯赋存状况、煤层爆炸危险性、煤的自燃性及地温情况 10 1.3.3 水文地质 11 1.4 矿（井）田勘探类型及勘探程度评价 13 第二章 井田开拓 1
