Abstract: Took Tongshan 5# ore mining technological design as the project example, economic and reasonable stripping ratio were calculated by using price method, elements of open pit slope were analyzed, bench height and final slope angle were the main parameters in open pit slope elements, mining technological design was done, provided references for similar open pit mining.

Key words: Remnant ore mining, Stripping ratio, Bench height, Final slope angle
