Abstract: Through deep analysis on the process of underground transportation，according to the characteristics of underground transportation，agent intelligent simulation technology was used to the model of underground mining transportation simulation，which made the result more close to the reality.Through the analysis and classification to the underground transportation and lifting，the process was decomposed into a series of discrete event.A Petri net model was established and every link of transportation was set an agent object which made the simulation more comprehensive and real.

Key words: Underground transportation, Agent technology, Petri net, Simulation
