摘　　要：对倾斜薄状矿体进行开采时,常常会面临采矿方法选择难的问题。某矿区内的铅锌矿体主要赋存于断裂带中,矿区内待开采的矿体属于倾斜薄状矿体。为了开采矿区内的铅锌矿资源,采用平硐+盲斜井的开拓方式,并根据矿区内矿体特征和开采技术条件,确定采用留矿全面采矿法对该铅锌矿进行开采。对留矿全面采矿法的采场矿块结构、采准、切割工程、回采落矿工艺进行了设计。结合相关经济指标,认为该采矿方法能够满足矿山实际生产需求,采用的留矿全面采矿法适合开采矿岩较稳固的倾斜薄状矿体,可为相关铅锌矿体的开采提供参考。When mining inclined thin ore bodies,it is often difficult to choose mining methods.The lead-zinc ore bodies in a mining area are mainly hosted in the fault zone,and the ore bodies to be mined in the mining area are inclined thin ore bodies.To mine the lead-zinc resources in the mining area,the development method of adit+blind inclined shaft is adopted,and according to the characteristics of the ore body and mining technical conditions in the mining area,the comprehensive mining method of shrinkage is determined to mine the lead-zinc mine.The stope ore block structure,mining preparation,cutting engineering,and mining and falling process of the comprehensive mining method are designed.Combined with the relevant economic indicators,it is considered that the mining method can meet the actual production needs of the mine.The comprehensive shrinkage mining method is suitable for mining the inclined thin ore body with stable mining rock,which can provide reference for the mining of related lead-zinc ore bodies.
