Abstract
An object of the invention of the application is to provide an autonomous travelling mine vehicle that can suppress a decrease in work efficiency when dust is generated at a work site. Therefore, the autonomous travelling mine vehicle includes a surrounding monitoring sensor that measures a three-dimensional point cloud of a terrain profile around the vehicle body, and a travelling route setting device calculates an undetected area representing a terrain profile part that the surrounding monitoring sensor cannot measure, calculates an alternative route on which the vehicle body can travel without passing through the undetected area on the basis of the positional relationship between the undetected area and the vehicle body, and updates the scheduled route with the alternative route.
