Abstract: In order to reasonably optimize the mine transportation and hoisting system，an AHP(Analytic Hierarchy Process)model of haulage and hoisting limiting factors was established based on the analysis of the factor limiting the transportation and hoisting operation in a certain mine by using the AHP.The weights of the limiting factors were obtained by constructing judgment matrix and solving the AHP model.The multistage lift was low efficient and had the largest weight of 35.2%.The shaft lacks of unified design and the transport efficiency at middle is lower.These two factors' weight occupied 15.04% and 14.55%，respectively.The rest of the factors were not up to 10%.The judgment matrix consistency of single order and the total order are checked as with good consistency.The results showed that it was feasible to obtain the relative importance of limiting factors in mine transport and hoisting transport system by AHP.The analysis results provided the basis for optimizing decision and some recommendations were given.The work should focus on improving the multistage slope lift way，accomplishing the uniform design in deep transportation promotion and paying attention to sublevel haulage.
