摘　　要：露天转地下矿山在露天减产期和基建期同时进行过程中,实现露天与地下的正常衔接是企业的首要任务。庙沟铁矿根据现场实际情况,设计北端帮部分矿体提前采出,缓解露天减产对企业的影响。根据矿体赋存条件,采用斜坡道开拓、汽车运输、两翼对角式通风。经论证,方案经济合理可行。For open-pit mine to underground during the procedure of reduction of open-pit output together with capital construction,the top priority for the enterprise is to achieve the normal engagement between open-pit and underground. According to the actual conditions on site in Miaogou Iron Ore,the paper designs the orebody at the northern end wall will be mined in advance to supply the reduced ore.According to the occurrence of the orebody,adopt slope ramp development,truck transportation,two-wing diagonal ventilation.After argument,this option is economical,reasonable,and feasible.
