1、中文题目:大平二矿3.0Mt/a新井设计外文题目:THE NEW SHAFT DESIGN OF DAPING NO.2 MINE(3.0MT/A)摘要大平二矿拥有两层可采煤层,煤厚分别是5.5m和14m。煤层东西走向约为4250m,南北倾向约为3000m,井田面积约为14.43 km2。平均倾角为7度。工业储量为3.82亿吨,设计储量为3.68亿吨,可采储量为2.55亿吨。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,设计严格遵守煤矿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
2、并列式。采煤方法采用走向长壁综合机械化采煤方法,采煤工艺是一次采全高。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。本次设计是大平二矿新井设计,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,力求设计出一个安全、高效的现代化矿井。关键词:单水平立井开拓;中央并列式通风;走向长壁采煤法;综采AbstractDaping NO.2 Mine can have a two-layer thick coal seam, and were 5.5m and 14m.
