Abstract: On account of problems encountered in actual productiont of the BWE continuous system in Zhahanao’er open-pit mine,Set?in the system shift,to analyze whether or not to proceed with continuous system,compared with discontinuous stripping technology about production cost and new investment;research on plane space arrangement，combine geological occurrence and adverse conditions encountered in actual production，analyse the best time to implement downgrade level layout.The results showed that:compared with the discontinuous technology,unit cost of the BWE continuous system is the lowest,the maximum payback period of the new investment will be 2.98 years,it is economical and reasonable to continue to use tBWE continuous system;combine selection of the final layout scheme,prove that the system efficiency can be improved by changing the space arrangement of the BWE continuous system,and the new layout scheme is advantageous to the production in the open-pit mine .
