The invention relates to a mine intrinsically safe reversing early warning device, and belongs to the field of coal mine safety early warning. The mine intrinsically safe reversing early warning device is characterized in that the reversing early warning device is embodied with an intrinsically safe characteristic. A whole set of devices is composed of an intrinsically safe power supply and a distance measurement display circuit, wherein the distance measurement display circuit is composed of two parts, that is an intrinsically safe reversing image part and an intrinsically safe infrared distance measurement alarm part. The mine intrinsically safe reversing early warning device has the greatest advantage of meeting the intrinsically safe requirement. The intrinsically safe reversing image device and the intrinsically safe infrared distance measurement alarm device adopt intrinsically safe designs. The whole device is powered by an intrinsically safe power supply, so that the intrinsically safe performance of the complete set of devices can be guaranteed. The mine intrinsically safe reversing early warning device is applicable to special occasions with inflammable and explosive properties under coal mines.
