[0002] Underground coal mine is a narrow working space with harsh environment. Coal mining, roadway support, coal transportation, equipment installation, and transportation of auxiliary materials are all completed in this small space, which brings great difficulties to coal mining operations and safe transportation. Put a lot of pressure on the downhole environment

With the promotion and use of rubber-tyred vehicles powered by explosion-proof diesel engines, domestic explosion-proof diesel engines have a large gap compared with foreign products in terms of high efficiency and exhaust gas treatment technology, and their own exhaust pollution and noise pollution have further caused coal mines. The deterioration of the working environment has caused great harm to the health of underground workers. At the same time, it has also buried a certain degree of safety hazards, and the lack of power in the oxygen-thin environment has become a bottleneck for the development of trackless auxiliary transportation and restricts my country. Weak link in the development of coal production

At present, the auxiliary transport vehicles used in underground coal mines basically retain the original handling and transmission forms of ground vehicles. The underground ramps have large fluctuations, and they need to go up and down the ramps many times within a few kilometers. Mechanical or hydraulic machinery is used. When the transmission mode is different, the driver frequently shifts gears and pulls the clutch during operation, which is prone to driving fatigue and has a certain impact on driving safety.

[0003] The combination of explosion-proof motors and energy storage devices can make auxiliary transport vehicles more flexible in configuration, operate in more working conditions, reduce pollution emissions in underground roadways, and develop new energy vehicles with low pollution, zero emissions, low noise, and green environmental protection. However, due to the large volume and weight of the special lead-acid batteries currently used in coal mines, the application on explosion-proof rubber-tyred vehicles has caused problems such as heavy machine weight, short mileage, long charging time, difficult matching of motors, and excessive battery discharge rate. , has become a bottleneck restricting the development of new energy vehicles in coal mines
