1、中文题目:肖家堡矿3.0Mt/a新井设计外文题目:THE NEW SHAFT DESIGN OF XIAOJIABAO MINE(3.0MT/A)毕业设计(论文)共130页(其中:外文文献及译文26页) 图纸共4张 完成日期 20xx年6月 答辩日期 20xx年6月摘要肖家堡矿拥有两层可采煤层,煤厚分别是8.2m和12.6m。煤层南北走向约为4000m,东西倾向约为3450m,井田面积约为13.8 km2,平均倾角为7。工业储量为3.79亿吨,设计储量为3.64亿吨,可采储量为2.56亿吨。本设计从矿井的开拓、开采、运输、通风、提升及工作面的采煤方法等各个环节进行了详细的叙述,设计严格遵守矿井
2、设计规范和煤矿安全规程。本设计采用立井单水平开拓,主井采用箕斗提升,副井采用罐笼提升,大巷采用集中布置。通风方式为中央并列式。矿井建井工期为23个月。采煤方法采用倾斜长壁综合机械化采煤方法,采煤工艺采用综采放顶煤。工作面支护方式为液压支架支护方式,端头支护采用端头支架。本次设计是肖家堡矿新井设计,地质资料都是在实习矿上搜集的,在指导教师的指导下,并合理运用平时及课堂上积累的知识,查找有关资料和文献,确保设计出一个安全、高效的现代化矿井。关键词:单水平立井开拓;通风;倾斜长壁采煤法;综采放顶煤AbstractXiao Jia Bao coal mine have a two-layer thic
3、k coal seam, which were respectively 8.2m and 12.6m. The length of this coal seam is about 4000m from north to south and 3450m from east to west, the coal mine field is about 13.8 km2 with an average inclination about 7degrees, the design reserve and the recoverable reserves of which are respectivel
4、y 379 million tons and 256 million tons, design reserves of 364 million tons. This design describes all aspects in detail from the mine exploration, mining, transport, ventilation to coal mining methods to exploit working face, and strictly follow the Design Standards and Coal Mine Safety Regulation
5、s.This design adopts shaft and single-level development, the main shaft lifts with skip, the auxiliary shaft hoist with cage, and the roadway adopts the centralized arrangement mode.The ventilation method adopts the central parallel mode. Mine well construction will be completed within 23 months. Th
6、e coal mining method is longwall mining to de dip, and the coal mining technology uses the fully mechanized top coal caving method. The working face supporting method adopts hydraulic support, the end support method uses the end bracket. The mine design is for Xiao Jia Bao new well under my instruct
7、ors guidance, and the geological datum are collected by the workers of the mine in the practice, during this design, the knowledge gained in class are reasonably used, whats more, the relevant data and documents are consult to make sure a safe, efficient and modern mine.Key words: Shaft and single-l
