摘　　要：柿竹园钨锡钼铋矿采用分段空场法和连续阶段大爆破崩落法回采矿床中心富矿带,给周边资源及下部开采带了一系列的生产问题。针对该矿开采技术条件、塌落区处理、采空区探查、露采优越性、露天境界优化、地采转露采的必要性和紧迫性、项目投资及等相关问题进行了分析研究,得出地采转大露采能很好地处理塌落矿岩,规避地采安全隐患,实现周边资源安全、高效、经济回采及优化配矿的结论,建议企业尽早实施大露采采矿工作。The sublevel open stoping method and the large blasting caving method with successive stages were used to recovery bonanza in the center of deposit in Shizhuyuan WSn-Mo-Bi mine,which caused a series of production problems for surrounding resource and deep mining.Therefore,mining technical conditions,treatment of collapse area,exploration of goaf,superiority of open-pit mining,optimization of open-pit boundary,necessary and urgency of open-pit mining,project investment and other related problems were analyzed and researched.The results showed that transferring from underground mining into open-pit mining could greatly manage collapse rock,avoid the security risks of underground mining,realize the safe,efficient and economic recovery of surrounding resource,as well as optimize the ore matching.Finally,it suggested company to implement open-pit mining as soon as possible.
