Including the residual column, stope lost to help, the main ore body up and down the small ore body and the main ore vein parallel to the plate of small veins and so on. For old mines with relatively complete mining and dressing systems and production equipment, exploring the available mineral resources, expanding industrial reserves, extending the production period, increasing ore production and making full use of mineral resources is a matter of economic and political significance
