1、摘要回村四矿拥有四层可采煤层,煤层和煤厚分别是1#(3.5)、2#(10.0)、3#(5.5) 3#(5.5)、 8#(5.5)。煤层南北倾向向约为4000m,东西倾向约为4000m,井田面积约为15.01 km2。平均倾角为4度。工业储量为5.15亿吨,设计储量为5.08亿吨,可采储量为4.89亿吨。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,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
2、架。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。本次设计是回村四矿新井设计,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:煤矿开采;开拓布置;运输;开采方式;通风AbstractBack to the village four mine four coal seam, coal and coal thickness were 1# (3.5),2# (10),3# (5.5)3# (5.5),8# (5.5).
