1、摘 要本设计是对南煤集团南庄矿15#八采区设计,其中主要内容有:采区上山布置方案的确定、采区巷道的布置以及采区通风风量计算和安全措施。本次设计为15#煤8采区。设计采用走向长壁采煤方法开采。回采工艺采用后退式、综合机械化放顶煤采煤法。作业制度为“四六制”,三班采煤、一班检修。工作面的设备有双端可调双滚筒采煤机、液压支架、可弯曲刮板运输机、破碎机、转载机等。采空区采用全部跨落法管理顶板。同时,由于该矿井是煤与瓦斯突出矿井,在采区巷道布置过程中,专门布置了一条瓦斯高抽巷,这样在保证采区工作面安全生产的情况下,还可以给矿井带来一定的经济效益。根据本采区的具体条件,采用单水平布置,且采区布置了三条主要
2、巷道,即胶带大巷、轨道大巷、回风大巷,服务于该采区各工作面。采区采用机械抽出式通风方法,混合式通风方式,其通风方式为“一进两回”,即“U+L”的通风方式。最后,该设计还编写了各种灾害预防措施及灾害发生后的避灾路线。此设计符合相关的法律法规,达到国家要求安全生产的各项标准。关键词:走向长壁采煤方法开采 单水平 抽出式通风方法AbstractThis design is founded ore in south coal group # 8 of 15 mining area design, the main contents are: the mountain mining area layou
