Abstract: Abstract: In view of vehicle hydraulic driven by hydraulic control defects existing in closed system of vehicle driving system of special explosion-proof diesel used in coal mine, in the study of the vehicle with full hydraulic drive based closed running system of electro-hydraulic control technology of non coal mines, design suitable for coal mine special explosion-proof diesel vehicle full hydraulic drive vehicle explosion-proof electric closed running control system and in the mining special explosion-proof hydraulic drive vehicle can be applied in the control system. After the promotion of a one-year experiment show that this system can realize the automatic matching of explosion-proof motor and hydraulic system, improve the utilization rate of engine power, can obtain the comprehensive performance than the existing hydraulic closed type walking system better. (climbing ability is improved by more than 10%, fuel consumption reduced by more than 5%).
