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