A mining work machine includes an obstacle determination device connected to a periphery detection device. If measurement points detected by the periphery detection device in a current cycle are equal to or greater than predetermined size thresholds equivalent in size to the mining work machine, these measurement points are put into a single obstacle candidate group. Based on relative speeds of the obstacle candidate at the measurement points and a traveling speed of the mining work machine, it is determined whether the obstacle candidate is a stationary object or a moving object, and whether the stationary object has been also detected by the periphery detection device in a preceding cycle. If a position of detection of the stationary object detected for the first time is equal to or smaller than a non-obstacle determination distance threshold, the obstacle determination device outputs the obstacle candidate as a non-obstacle.
