Disclosed is a start delay warning device for a coal mine down-hole mine vehicle. The start delay warning device comprises a pilot oil circuit. The pilot oil circuit is provided with a pressure oil inlet and an oil outlet. A hydraulic operated directional valve, a sequence valve and an adjustable restrictive valve are installed on the pilot oil circuit between the oil outlet and the pressure oil inlet sequentially. A pressure oil inlet of the sequence valve is connected with a pressure oil branch I. A pressure oil inlet of the adjustable restrictive valve is connected with a pressure oil branch II. A delay sound-light warning device is arranged between the pressure oil branch I and the pressure oil branch II. The part, between the sequence valve and the adjustable restrictive valve, of the pilot oil circuit is provided with an energy accumulator. The start delay warning device can be applied to all coal mine down-hole hydraulic drive vehicles. The delay sound-light warning device is integrated into a vehicle braking system and a hydraulic pilot system, so that the vehicles are forced to conduct sound-light warning automatically before starting and be started in delay. The accidents of casualties surrounding the vehicles due to impatience driving can be effectively avoided, and the safety of the coal mine down-hole mine vehicle is greatly improved.
