Abstract:

In order to improve the efficiency of underground mine’s transportation，the running route and distance of electric locomotive must be considered for comprehensive analysis.Under the premise of considering the transportation task of every-shift，a multi-objective route optimization model was proposed with the total amount and the total haul distance of electric locomotive as the optimization goal.The NSGA-II is a commonly used algorithm to solve the problem of multi-objective optimization，it was applied to optimize the route of underground mine’s transportation for the first time，and MATLAB software was used for emulating the solving process.The results show that the best transportation route is quickly gotten by using this method， and it provides basis and assurance for the route arrangement of mine’s transportation.Taking a copper mine in Yunnan Province as an example，the total amount is 1 348.4 t·km and the total haul distance is 2 995.7 m when in the best transportation route.
