1、摘 要本设计是针对湘煤集团唐冲煤矿所做的矿井初步设计。唐冲煤矿自然地质条件中等,可采煤层三号煤平均厚2.76m,倾角一般为1025左右。矿井正常涌水量为118m3/h,最大涌水量为179 m3/h。矿井绝对瓦斯涌出量为10.78 m3/min,相对瓦斯涌出量为11.35 m3/t,预测为高瓦斯矿井。煤尘具有爆炸危险性,煤层没有自燃发火倾向。井田东西长1.82.1km,南北宽约为4.5km,面积约10km2,设计井田的可采储量为3032万t,设计年产量为0.45Mt,服务年限为51a。本设计矿井采用斜井两水平水开拓,采区式准备方式,采区内采用走向长壁采煤法,全部垮落法管理顶板,矿井前期采用对角式
2、通风。主要对矿井开拓方式、准备方式、采煤方法进行了初步设计,对矿井运输、通风、排水等生产系统进行了设备选型计算,对矿井各个生产系统的生产过程进行了描述,并对矿井各个生产系统和各生产环节之间的相互联系和制约关系进行了有关说明。关键词: 立井 塘冲煤矿 高瓦斯 走向长壁采煤法Abstract This preliminary design is designed for Tang Chong mine of in HuNan province. The natural geological condition is medium, the mining seam :the average thic
3、kness is 2.76m,.Generally,the dip is 1025.Normally,the water-holding capacity is118 m3/h,the largest water-holding capacity is 179 m3/h.The gass absolute emission is 10.78m3/min,the gass contrast emission is 11.35m3/t. This is very dangerous, this mine is prophecied as high prominent gas. The coal-d
4、ust has explosion hazard, the seam doesnt have spontaneous combustion tendency. The spontaneous combustion is appraised for three kinds. The field is4.5km long along the east-west direction and is .82.1km width along the south-north direction. The area is 9 square .The designed fields mining is 3032
5、million ton. The designed annual is 0.45Mt, and it will serve for 51a. This mine uses two level to climb the mountain .Its ways to prepare is using the area of the mine .In the area of the mine, the method of mining is using walking toward the long wall .The method of manage the roof is using collap
6、se. In the front period of the mine uses the central paratactic type to ventilate. This preliminary design is mainly for the Pioneering way , prepare types, mining types. This design also chooses the model of the transportation system, ventilation system, drainage systemact. And, it also describes t
7、he production process of every system in the mine. This design explain the relationship and restrict relationship between every production system and every production links.Key words: Vertical Shaft,Tong Chong mine,high gas,two level climb the mountain, the walking toward long wall miningIX目 录1 矿区概述
