摘　　要：某钨矿山深部矿体形态复杂、产状多变,目前采用的浅孔留矿法、留矿全面法难以满足安全生产需要。为提高资源回收率和解决管理难度大等问题,在原采矿方法的基础上,联合采用中深孔分段崩落法,合理划分矿块,优化采场参数,合理安排采、切、出作业。新方法提高了作业安全系数,采场回采周期缩短了0.5~1.5年,减少矿柱、矿壁损失,采矿损失率降低了约5%,采矿贫化率降低了约6%,解决了原采场回采矿量大、周期长、存窿矿过度集中、出矿效率低等问题,也显著地提高了矿山经济效益。这种联合采矿方法可为矿区今后的生产和同类型的矿体开采提供一定参考与指导。The deep orebody has complicated forms and shapes. The current shallow hole stoping method and shr/nkage stoping method can＇t meet the production methods. To improve the resource recovery rate and management problems, sublevel caving method is applied with reasonable orebody classification and stoping parameters optimization. The new mining method increases the production safety factors, with stoping cycle reduced by 0.5 ~1 year, reduced pillar and wall loss. The mining loss rate and dilution rate are reduced by 5 % and 6 % respectively. The economic benefits are markedly increased.
