During the operation of the mine car， it is difficult for the driver to fully concentrate， and in case of sudden accidents， they may not be able to respond in a timely manner， leading to collision accidents. Therefore， based on 4D light field ranging and artificial intelligence technology， an anti-collision warning system has been designed. The results show that the system can achieve efficient and accurate obstacle recognition and distance estimation， and ensure the safety of mine car travel.It can complete collision prevention tasks in a relatively short time and is not affected by adverse weather conditions. This system provides a new anti-collision solution for industrial mine cars and contributes to the development of smart mines.
