Comparing and Researching of Exploiting Project for Dafeng Strip Mine

According to the reality problem of producing continuing between Dafeng and Zhongcao mining area and how to mine in the Dafeng mining area , in the meantime , under the limit of Dafeng mining area producing condition , the article researches and compares the exploiting project of Dafeng mining area in detail , then puts forward three projects which are based on the reality of Dafeng Strip Mine. In the paper ,these three projects are compared detailedly and studied deeply from following sides of operational stripping ratio?mining area continuing?inner dumping and appending of device etc . Finally , the optimal project is picked out , which is fit for the reality of production spot and significant to direct the production.
