1、摘要锦界二矿拥有三层可采煤层,煤厚分别是5.6m、14.1m和12.2m。煤层走向约为5km,倾向约为4km,井田面积约为20km,平均倾角为0.4。工业储量为8.93亿吨,可采储量为6.34亿吨。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,设计严格遵守矿井设计规范和煤矿安全规程。本设计采用斜井单水平开拓,主井采用皮带运输升,副井采用无轨胶轮车运输,大巷采用分层大巷布置。通风方式为中央并列式。矿井建井工期为18个月。采煤方法采用走向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。本次设计是锦界二矿新井设计,地质资料都是
2、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:单水平斜井开拓;通风;走向长壁采煤法Abstract Jin Jie coal mine have a three-layer coal seam, which were respectively 5.6m、14.1m and 12.2m. The length of this coal seam is about5km from north to south and 4km from east to west, the coal mine field is
3、 about 20 km2 with an average inclination about 3 degrees, the design reserve and the recoverable reserves of which are respectively893 million tons and 634million tons. This design describes all aspects in detail from the mine exploration, mining, transport, ventilation to coal mining methods to ex
