深井缓倾斜难采薄矿脉开采新工艺

New mining technology of deep well gently inclined hard-to-extract thin veins

采用水压支柱护顶、帷幕隔离快速充填采矿新工艺 ,使采场空区的密闭与采矿作业同步进行 。

Such new technologies as hydraulic prop sustaining and fast filling method with curtain separation were adopted so as to enable the synchronous sealing of mined out area and the mining operation, and mining efficiency was increased substantially
