1、摘 要本设计包括三个部分:一般部分、专题部分和翻译部分。一般部分为木瓜煤矿1.5Mt/a新井设计。木瓜煤矿位于山西省方山县境内,交通便利。井田走向(东西)长约3.69km,倾向(南北)长约3km,井田总面积为10.32km2。主采煤层为9号、10号煤,平均倾角为6,煤层平均总厚为9.13m。井田地质条件较为简单。井田工业储量为14204万t,矿井可采储量10150万t。矿井服务年限为52.1a,矿井正常涌水量为40m3/h,最大涌水量为66 m3/h。矿井绝对瓦斯涌出量为5.67 m3/min,为低瓦斯矿井。井田为斜井单水平开拓。大巷采用胶带运输机运煤,辅助运输采用无轨胶轮车设备。矿井通风方式
2、为混合式通风。矿井年工作日为330d,工作制度为“三八”制。一般部分共包括10章:1、矿区概述及井田地质特征;2、井田境界和储量;3、矿井工作制度及设计生产能力;4、井田开拓;5、准备方式-带区巷道布置;6、采煤方法;7、井下运输;8、矿井提升;9、矿井通风与安全技术;10、矿井基本技术经济指标。专题部分题目是近距离煤层下煤层安全开采技术研究,主要是研究了近距离下煤层回采巷道的合理布置与支护技术。翻译部分主要内容为关于煤矿用胶带输送机,英文题目为:Research of Fire Hazard Critical Guidelines of Mine Use Belt Conveyor and
3、Automatic Fighting Fire System。ABSTRACTThis design includes of three parts: the general part, special subject part and translated part. The general part is a new design of Mugua mine. Mugua mine lines in West of Fangshan county in ShangXi province. The traffic of road and railway is very convenience
4、 to the mine. The run of the minefield is 3.69km,the width is about 3km,well farmland total area is 10.32km2.The nine and ten is the main coal seam, and its dip angle is 6 degree. The thickness of the mine is about 9.13m in all. Geologic structure of coalfield is simple.The proved reserves of the mi
5、nefield are 142.04 million tons,and the recoverable reserves are 101.50 million tons. The designed productive capacity is 1.5 million tons percent year, and the service life of the mine is 52.1 years. The normal flow of the mine is 40m3 percent hour and the max flow of the mine is 66 m3 percent hour
6、. The mineral well gas gushes is lower, It is a low gas mineral well. The mine is a single level in an inclined well to expand. Te central laneway use Belt Conveyor to transit coal, mining trucks are used for accessorial transportation in te roadway.Te ventilation mode of this mine is composite form
7、.The working system “three-eight” is used in the Mugua mine. It produced 330 d/a.This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.development engineering of coalfield; 5.The layout of belt
