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。一般部分为平煤四矿5.0Mt/a新井设计。平四矿位于平顶山市西北约6km,交通便利,井田走向长约9.6 km,倾向长约7.2km,井田总面积为69.8km2。主采煤层为戊8、戊10煤层,倾角6-9,平均8.1。煤层平均厚度分别为3.60 m、3.70 m,井田地质条件较为简单。井田工业储量为624.9Mt,矿井可采储量475.18 Mt。矿井服务年限为67.8a,涌水量不大,矿井正常涌水量为200 m3/h,最大涌水量为340 m3/h。矿井相对瓦斯涌出量为9.56 m3/t,为低瓦斯矿井。开拓方式为立井两水平暗斜井延伸。大巷采用胶带运输
2、机运煤,辅助运输采用矿车运输。矿井通风方式为中央并列式通风。矿井年工作日为330 d,工作制度为“四六”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、设计生产能力及服务年限;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。专题部分题目为简析煤矿巷道断面设计思路。翻译部分题目为在长壁放顶煤采煤法中通过仿真模型优化工作面设备组合。关键词:立井;带区;中央并列式通风ABSTRACTThe three parts is included in this design,i.
3、e.,the general part, special subject part and translation.The general part is a new design of PingSi mine with a production of 5.0 million t/a. PingSi mine lines in PingDingshan County, HeNan province. The traffic of road and railway is very convenience to the mine. The run of the minefield is 9.6 k
4、m ,the width is about 7.1 km, well farmland total area is 69.8 km2. No. 8 and No. 10 are the main coal seam, and its dip angle is 69, 8.1 for average. The thickness of the mine are about 3.6 m and 2.7 m respectively. The geological conditions of the minefield is relatively simple.The proved reserve
5、of the minefield is 624.9 Mt. The recoverable reserve is 475.18 Mt. The designed productive capacity is 5.0 Mt/a, and the service life of the mine is 67.8 years. The normal water flow of the mine is 200 m3/h and the max flow of the mine is 340 m3/h. The relative gas emission rate of the mineral well
6、 is 9.56 m3/t, for low gas mineral well.The well farmland is a single level with a shaft to expand. The coal is transported by the belt conveyer in the main roadway and 1 t mine car is used as the auxiliary transportation equipment. The way of mine ventilation is central boundary ventilation.The wor
7、king system “four-six” is used in Kaiyuan mine. It produces 330d/a.This general part 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.Preparation typestrip stri
