2、煤矿设计生产能力为 300 万 t/a,服务年限为 68 年,对第一水平选择了立井开拓方案,首采区的采煤方法采用倾斜长壁采煤法,综合机 械化回采工艺。辅助运输系统与主运输系统相分离,其中辅助运输系统采用了国际上先 进的辅助运输设备单轨吊,可满足人员、机械设备、材料和矸石的运输,无需中间转载, 可从井底车场直达工作面。矿井一水平采用两翼对角式通风系统。 总之,通过技术经济等多方面的比较得出本设计的开拓方案、采煤方法等均能满足 矿井的开采需求。 关键词:关键词:立井开拓;条带式;单一倾斜长壁采煤法;综合机械化采煤;两翼对 角式通风 III Abstract: :This design introd
