1、摘要晓明3矿拥有三层煤,煤层和煤厚分别是7(3.4)、8(5)、9(3.2)。煤层南北倾向约为4.1.km,东西走向约为4.1km,井田面积约为17.46 km2。倾角为8.1度。工业储量为276.14Mt,可采储量为188.5Mt。本设计说明书从矿井的开拓、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,设计严格遵守设计规范和煤矿安全规程,整个矿井采用了先进的皮带运输和矿车运输,提高了运输能力,为矿井的增产打下了良好的运输基础。采煤方法采用倾斜长壁综合机械化采煤方法。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。本设计采用立井多水平上山以及上下山开拓,主井采用箕
2、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。本次设计是晓明3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,力求设计出一个高产、高效、安全的现代化矿井。关键词:煤矿;开拓;运输;开采;通风AbstractGeomantic a three-layer coal mine has coal seam, and were 7 (3.4), 8(5), 9(3.2), Coal north-south about 4.1 km, things tend to run about 4.1 km, approxim
