1、山西大同大学本 科 生 毕 业 设 计中文题目：范各庄矿 9 号煤层 1.8Mt /a 新井设计英文题目：1.8Mt /a Nii design of No. 9 coal seam offan Ge Zhuang mine学院： 煤炭工程学院姓名：学 号：专业：采矿工程班 级：16 采矿专升本二班指导教师：职 称： 完成日期：2018 年05月27日摘要全套图纸加扣 3346389411或3012250582这次设计是围绕范各庄矿 9#煤层地质条件下做的矿井设计，本矿井地质条件较为简单，但同时存在陷落柱，对此留了 30m 保护煤柱，煤层平均厚度 5.12m，平均倾角 10，自然发火期较长，煤层具有爆炸性，属低瓦斯矿井。井田内工业储量 1.83108 吨，可采储量 1.28108 吨，根据煤层赋存条件设计矿井年生产量为 180 万吨每年，服务年限约 54 年。矿井工作日为 300 天，采用四六制作业，三班采煤一班检修。矿井布置一个综采工作面保证全矿井的产量，长度 260m，煤在运输大巷的运输采用带式输送机运输。经过技术经济比较，选择了双立井开拓，主副井各一个，位于工业广场内，主井采用多

2、绳摩擦式双箕斗提升，直径 6.5 米，副井采用罐笼提升，直径 6 米。首采区为位于中部的 82 带区。首采区采用倾斜长壁一次采全高后退式综合机械化采煤方法。工作面进刀方式采用端部斜切进刀割三角煤。工作面采用了 ZZ990/29.5/50 型液压支架，支护方式为及时支护。安全技术措施包括井下瓦斯预防、顶板管理、水灾预防、火灾预防、煤矿爆炸的预防及粉尘防治措施等。关键词:端部斜切进刀；及时支护；安全生产ABSTRACTThis design is designed around the geological condition of 9# coal seam in fan Gezhuang coal mine. The geological condition of this mine is relatively simple, but there is a collapse column at the same time. It has 30m protection pillar, the average thickness of coal seam is 5.12m, the aver

3、age dip angle is 10 degrees, the natural firing period is longer, the coal seam is explosive and belongs to the low gas mine.The industrial reserves in the well field are 1.83 x 108 tons, and the recoverable reserves are 1.28 * 108 tons. According to the coal seam conditions, the annual production capacity of the mine is 1 million 800 thousand tons, and the service life is about 54 years. Mine working day is 300 days, using 46 system operation, three class coal mining one maintenance. The mine a

4、rranges a fully mechanized coal mining face to ensure the output of the whole mine. The length is 260m. The transportation of coal in the transportation main road is carried by belt conveyors.Through technical and economic comparison, two vertical wells are selected and one of the main and auxiliary wells is located in the industrial square. The main shaft is raised with a multi rope friction Double Skip, with a diameter of 6.5 meters. The auxiliary shaft is raised by a cage with a diameter of 6

5、 meters. The first area is located in the middle two zone in the middle. The first mining area adopts the inclined longwall once mining full height backward type comprehensive mechanized mining method. The feed way of the working face is cutting the triangle coal with the end oblique cutting feed. The ZZ990/29.5/50 hydraulic support is adopted in the working face, and the support is timely support.Safety technology measures include underground gas prevention, roof management, flood prevention, f
