1、 设计总说明 本设计包括两个部分:一般部分和专题部分。祁南矿 1.8Mt/a 新井设计,全篇共分为十个部分:矿井概括及井田地质特征、井田境界及储量、矿井工作制度和设计生产能力及服务年限、井田开拓、采区巷道布置、采煤方法、井下运输、矿井提升、矿井通风与安全和矿井主要经济技术指标。祁南矿其井田南北长平均约 3.2km,东西长约 7.8km,面积约 24.96km2。井田内的主要可采煤层为 32煤、7 煤、10 煤,煤层赋存稳定,首采煤层 32煤平均厚度 2.8 米。倾角平均为 11。井田内工业储量 268Mt,可采储量 236Mt。矿井平均涌水量为 28m3/h,相对瓦斯涌出量 0.5m3/t,属
2、于低瓦斯矿井,煤层没有爆炸危险性。祁南矿设计生产能力 1.8Mt/a,服务年限 93 年。采用立井两水平开拓,暗斜井延伸,由于煤层埋藏较深,故第一水平标高-550m,第二水平标高-750m。矿井一水平采用上山开采,二水平采用上下上开采。工作面均采用走向长壁综合机械化开采。矿井按一井一面,安全高效的原则布置一个综采工作面跨上山回采,尽可能多的采出煤炭资源,降低煤损。工作面长度 200m,矿井的通风方式采用中央边界式。专题部分是综采工作面复合顶板控制技术。关键词关键词:立井两水平;采区;走向长壁综合机械化开采 Design General Information Qinan Mine 1,800,
