The invention discloses a mining liquid carbon dioxide cooling and fire preventing and extinguishing system which is mainly composed of a liquid carbon dioxide low-temperature storage tank, a boosting vaporizer control system and a mining platform trolley. The liquid carbon dioxide low-temperature storage tank comprises an inner liner and an outer liner, and is connected with the boosting vaporizer control system through a boosting device and a liquid inlet device. The liquid carbon dioxide low-temperature storage tank and the boosting vaporizer control system are disposed at the upper end of the mining platform trolley. The mining liquid carbon dioxide cooling and fire preventing and extinguishing system is high in volume, carries much carbon dioxide and is suitable for extinguishing of a fire in a large downhole space. The system is provided with the boosting system, the intensity of carbon dioxide jet instantaneously is high, and the fire can be extinguished fast. Meanwhile, the system is simple in structu
