九里山煤矿矿井通风设计（毕业论文）.doc

文档介绍：河南理工大学毕业论文1九里山煤矿矿井通风设计摘要:本设计是焦煤集团九里山煤矿矿井通风系统的设计,在本井田范围内,地质条件简单,涌水量和***涌出量大,有突出危险,,服务年限60a,开拓方式为竖井开拓,采用走向长壁倾斜分层下行垮落采煤法进行回采。在矿井一水平的通风设计中,选用两翼对角式通风(也可看作分区式通风),计算了矿井需风量和两个时期的通风阻力,并选择了主要通风机,计算了吨煤通风电费,绘制了通风系统图和通风网络图,同时得出了几个关于通风设计的结论。本设计充分结合实际情况,积极采用切实可行的先进技术,为整个井田的安全生产奠定了良好的基础。关键字:煤矿矿井通风设计对角通风河南理工大学毕业论文2ThefirststepdesignofjiulishanmineventilationAbstract:,,-spanof60-,,selectstwowingsoppositeanglestypetoventilate(alsomayregardasdistricttypetoventilate),therespectivecalculationoftheventilationresistanceineasyanddifficultsituation,theselectionofthemainfan,putationofelectricalconsumptionforone-toncoal,,:CoalMineventilationDesignVentilationofoppositeangle河南理工大学毕业论文1目录1绪论..........................................................................................................................................................................................................................................................................................................................22基本概况...................................................................................................................................................................................................................................................................................................................................................
