1、摘要煤炭是我国最主要的一次性能源,也是我国战略上最安全和最可靠的能源,在国民经济中占有重要的战略地位,它的重要战略资源地位无法动摇。煤炭在世界一次能源消费结构中占20%以上,我国也是典型的多煤少油国家。本课题针对的主要方向为矿井机电设备。要实现高产高效的采煤,必须进行正确的机电设备选型。介绍了矿井概况,包括矿井的煤层赋存情况,水文地质情况,矿井开拓方式,通风排水压气系统,运输提升系统,矿井供电系统和生产管理系统。根据课题的设计要求,本设计主要从矿井地理位置,井田走向,顶底板条件,水文地质,矿井开拓系统,通风及排水要
2、求,主副井系统,主运输系统等矿井基本情况出发,进行采煤机选型计算,乳化液泵站选型计算液压支架选型计算,刮板输送机选型计算,通风设备选型计算,排水设备选型计算,皮带输送机选型计算,主井提升设备选型计算。并绘制三机配套图,泵房布置图,皮带输送机布置图。关键词:矿井机械化;选型设计;设备配套;运输提升;通风排水206ABSTRACTCoalisChina'smostmajorone-timeenergy,Chinaisthestrategicmostsafeandreliableenergy,inthenationale
