The reasonable crusher shifting space should ensure that the comprehensive production cost of the open pit is the lowest. Factors affecting crusher shifting space were analyzed and economic indexes, system links composing and disposal scheme were put forward dealing with semi-continuous system management. The study show that the reasonable shifting space must guarantee the crusher shifting costs compensated by saving the transportation costs. At the same time, the stope space restrict must be taken into consideration, to avoid the situation of advancing stripping and lagging in-dump caused by the best abilities of crusher disposal. Conclusions drawn from this research demonstrated that the lowest production cost should be the final target in the crusher shifting space project, while the shifting cost compensation and the slope space restriction are the boundary conditions, by which the optimized outcome can be confirmed synthetically. A Case study shows that the crusher shifting space determined by the multi-factor synthetically method is 180 meters farther than that confirmed by the traditional economic principles.
