Abstract: According to component of mine production cost，the five-in-one system of technology innovation was built，and the five aspects for realizing cost reduction and yield increase was put forward，including the innovation of mining method as the core，the optimization of mineral processing technology as focus，the innovation of filling process as the support，the construction of intelligent mine as base，and energy saving and emission reduction as the guarantee.Firstly，the cost gap between mine enterprises at home and abroad were introduced；Then，the five-in-one system for the cost reduction and yield increasing were discussed specifically from aspects of principles，technical characteristics，innovative approaches and applicability.The results of reducing cost and increasing yield based on technology innovation were summarized.Finally，the urgency of reducing cost and increasing yield were emphasized.The technology innovation method provided reference for mine enterprise to improve economic efficiency.

Key words: Technology innovation, Mine production technology, Cost reduction and yield increase, Energy-saving and emission-reduction
