Study on key controlling factors and countermeasures of production costs in Wulongquan mine based on grey correlation degree

According to the actual demand of reducing the production costs in Wulongquan mine,Deng's relational degree,T's correlation degree,slope correlation degree and C-MODE association degree are adopted respectively to analyze the correlation degree between production costs and the influence factors based on different non-dimension process.The result shows that controlling factors of production costs have varied with different non-dimension process and grey correlation degree algorithms.Finally,the key controlling factors of production costs are determined as labor costs,material costs and depreciation costs considering the actual situation of Wulongquan mine.And what's more,some reasonable proposals for the control of production costs are put forward to reduce and control production costs for the mine.
