摘要
阿尔登铅锌矿采用浅孔留矿法回采,安全性差,贫化损失大,生产能力小,需进行采矿方法优化选择。根据矿山开采技术条件,初步选择了适合阿尔登铅锌矿的采矿方法。通过技术经济比较,推荐采用分段空场采矿法进行回采,采场生产能力250~300t/d,矿石损失率20%~25%,贫化率15%~20%。研究成果对同类矿山采矿方法选择具有一定的借鉴和指导意义。
Shallow-hole shrinkage mining method was used in Alden lead-zinc ore,with poor safety,big dilution and loss ratio,small production capacity,therefore it should be optimized.Several possible mining methods were selected according to mining technical condition of deposit.Sublevel open stope method was recommended as the best by conducting echnical and economic comparison.The stope production capacity was 250-300 t/d,the ore loss ratio was 20%-25%,and ore dilution ratio was 15%-20%.By the way,the research achievement has a certain reference and guidance significance to the selection of mining methods for similar mines.
