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 deviceis disposed at a height where it can detect each small vehicle, while the second obstacle detection deviceis 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 deviceand second obstacle detection device, a detection processing devicedetermines whether an object is a small vehicle or a large vehicle.
