Abstract
When large vehicles and small vehicles travel together in a mine, they are distinguishably detected. On a haulage vehicle for a mine, a first obstacle detection device and a second obstacle detection device are disposed. The obstacle detection devices are disposed so that they have detection directions oriented in a same direction in horizontal planes, respectively. The first obstacle detection device 111 is disposed at a height where it can detect each small vehicle, while the second obstacle detection device 112 is disposed at a height where it can detect each large vehicle without detection of any small vehicle. On the basis of detection results of the first obstacle detection device 111 and second obstacle detection device 112, a detection processing device 120 determines whether an object is a small vehicle or a large vehicle.
