Abstract: To solve the problem of moving plan of semi-mobile crusher that applied in deep open pit with semi-continuous deploitation transportation，an optimization algorithm is proposed，basing on transportation model of time and space.According to mining and stripping progress plan，all possible moving plans are enumerated，and comparable minimum overall cost of each plan is calculated.The best economic plan is selected in order to optimize transportation organization and reduces the transportation cost of mine production.The software system basing on research conclusion is developed to improve accuracy and efficiency of similar engineering design.

Key words: Semi-continuous deploitation transportation, Semi-mobile crusher, Moving increment, Moving period
