某地下矿山上下矿体同时开采的安全性协调

Safety Coordination of Simultaneous Mining of Upper and Lower Ore Bodies in an Underground Mine

针对国内某地下金属矿山,通过确定开采范围及对象、开采技术条件分析、采矿方法选择、矿块布置、矿块生产能力分析及矿块生产搭配协调,来保障上下主矿体采用空场法同时开采的安全性。该文的研究对于地下矿山上下矿体采用空场法同时开采时,上下采区安全关系的协调具有一定的指导作用。

For a certain underground metal mine in China,the safety of simultaneous stoping for the upper and lower orebodies using the stope method is ensured by determining the mining range and objects,analyzing the mining technical conditions,selecting mining methods,designing ore block layout,analyzing the production capacity of the ore blocks,and coordinating the production matching of the ore blocks.The study in this paper provides guidance for coordinating the safety relationship between the upper and lower mining areas when the stope method is applied simultaneously to the upper and lower orebodies in underground mines.
