Abstract:

At present，because the surface of a plurality of small mine which surround around the Jiaojia gold main mining area is not allowed to collapse，there are a series of problems，such as filling preparation difficult，low efficiency and high production costs，etc.This paper expounds the mode that use the mature cemented filling system of the main mining area for the main mining area and surrounding small mining area filling service.At the same time，by focusing for sand，sand storage，centralized filling，completely solve the disadvantage of the surrounding small mine filling preparation system.The successful application of the model provides protection for mining enterprises making full use of resources and exploitation of resources，improves the economic and social benefits，and provides a reference for other mines.This model has a good application prospect.The effect is significant.

Key words: Multi mining area, Filling system, Integration efficiency
