Abstract
Based on actual data of a domestic open-pit mine, the probability distributions of the three key time parameters such as truck's travel time, shovels loading time and crusher's unloading time in open-pit mine truck dispatching were analyzed by Stat: Fit software. The conclusion indicates that truck's travel time accords with normal distribution, shovel's loading time accords with lognormal distribution, log-logistic distribution and inverse Gaussian distribution, and crusher's unloading time is relatively stable so that it can be seen as a constant.
