For optimizing the cutting depth of spiral drum type cutting head, the relations among collecting ratio, interfusing ratio of mullock and cutting depth of the mining cobalt-rich crusts in ocean were discussed. Furthermore, the multi-extremum problem about cutting depth was analyzed in mining at a certain interfusing ratio of mullock. Through introducing genetic algorithm (GA), the cutting depth-control problem when the collecting ratio is maximized by controlling the interfusing ratio of mullock was solved with global-optimization-search algorithms. Then optimization theory for cutting depth in mining cobalt-rich crusts by GA, and computer programming were given to realize the algorithm. The computation result of actual data proves the validity of this method.
