Study on Restricting Factors about Production Scale based on Grey Correlation Degree in Wulongquan Mine

Abstract

According to the actual demand of enlarging production scale and the present production condition in wulongquan mine, the production costs is stubbornly high and becomes a key factor of restricting production scale. In order to find out the restricting factors of production scale, grey slope correlation degree has been adopted respectively to analyze the grey incidence order between production scale and the influence factors such as materials costs, spare parts costs, energy costs, labour costs, repair costs and depreciation costs. And what's more, the key restricting factors of production scale have been determined to be repair costs, labour costs and materials costs by describing objectively the relationship between production scale and influence factors. The analyzing result is in line with the actual situation and the production scale of mine can be drawn up according to the basic information.
