Abstract: In view of the characteristics of regional mineral deposit mining，complex transportation system network and difficult to control transportation costs，a optimization model of regional mine transportation system based on complex network planning is constructed.Under the condition of regional exploitation，the comprehensive transportation system is integrated to realize the high efficiency，economy and scientific validity of regional mine transportation system.Based on analyzing the requirements of technical and economic index,the relationship between spatial location and establish the principle of system optimization,the system network diagram is established,the optimization model that considering the stope distribution,transportation methods,transport links and other factors are proposed,which goal is minimum comprehensive transportation cost.The global optimal scheme of regional underground mine transportation system is obtained by using computer technology and network flow theory.Taking a metal mine in our country as the study example,the performance of the optimization model proposed in this paper is verified,the optimal regional transportation route is obtained and the lowest transportation cost is calculated.The study results show that the optimization model established in this paper can not only meet the requirements of comprehensive management and intensive operations,but also can ensure the safe,economic and efficient operation of the mine transportation.
