Blasting To Primary Crushing Cost Optimize Research Of Wang Guan Ying Limestone Mine

Saving energy and reducing cost are effectual measure of develop corporation and buildup ability of competition. This paper is cost optimize research about the course of blasting to primary crushing to Wang Guan Ying limestone mine.Wang Guan Ying limestone mine is the base of Ji Dong cement stock limited company and supply primary crushed limestone to company. This task is looking blasting and primary crushing as the all and the one to research and find mutuality relation of blasting granularity and primary crushing cost to make sure cost distributing of blasting to primary crushing. These are using regress analysis and via granularity mensuration, data collect, calculate analyse. Blasting to primary crushing include blasting, loading, transportation, again crushing and primary crushing. This is principia that the total cost is the lowest in the research course and assure the model of average granularity and blasting cost, primary crushing cost, loading cost, loading efficiency, transportation efficiency, at last assuring total cost model that it is a function model about average granularity. We can make assure cost in the different extension to using total cost model.This paper make the method of granularity mensuration better in the course. The mine mensuration method include sift analyze, granularity ruler, photograph method, video photograph and high speed photograph, on the base of these method we make sure mensuration method using granularity ruler and photograph method, this method called include photograph method of granularity ruler. This method adapt to granularity mensuration of surface mining.This paper educes the cost model of blasting to primary crushing and use about six months to measure and analyse. At last, we educe the best circumscription of granularity, viz when average granularity within 210mm to 230mm, so the cost will be saved 154.22 wan Yuan every year.The research method and result are important direction meaning to production and have better use for reference meaning for other mining.
