1、摘要晓明一矿拥有两层煤,煤层和煤厚分别是分别为5煤(平均厚度5m),2煤(平均厚度9.8,与5煤间距30m)。煤层东西走向约为3.9km,南北倾斜约为4.12km,井田面积约为15.57 km2。倾角在12度。工业储量为2.4亿t,设计储量为2.31亿t,可采储量为1.6亿t。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,整个矿井采用了采区以及带区的准备方式,提高了开采能力,为矿井的增产打下了良好的运输基础。采煤方法采用走向长壁综合机械化放顶煤采煤方法以及倾斜长壁综合机械化放顶煤采煤方法。工作面支护方式为液压支
2、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。通风方式为中央分列式。本次设计是晓明一矿新井设计,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ABSTRACTXiaoming mine has two layers of coal, coal bed and coal thickness, respectively, were 5 coal (average thickness of 5
