Abstract: Abstract: the coal resource is still one of the main energy sources in China at the present stage, but the special environment in the coal mining process leads to the occurrence of safety accidents frequently. To happen after the mine environment problems such as complex, dark, poor communication, in order to make the robot to avoid to reach the destination within the roadway barrier smoothly, this paper puts forward A kind of based on the JSP (jump point search) —A * algorithm, at the same time of guarantee to select the optimal path, greatly reducing the traditional A * algorithm in the process of pathfinding extension of the node. Laboratory simulation results show that the improved A* algorithm can improve the speed of finding the optimal path by about 2 times compared with the traditional A* algorithm, which has far-reaching guiding significance in practical industrial production.
