Study on optimization of semi-continued stripping technique in Buzhaoba Surface Mine

According to needs of the stripping technology in fifth period extension and the stripping characteristic of marl, Proposing four kinds of matching mode between new and the existing semi-continuous system, are independent distribution, unite arrangement but independent feeding, independent distribution and feeding, and canceling continuous technology system. Comparing these ways, eliciting unite arrangement is superior plan in initial stages of semi-continuous,truck-crushing station system and bucket wheel are arrangement in parallel,are respective feeding. The continuous system is canceled later, it will predigest the stripping technology of marl.
