Wet and slippery pavement braking system for mining dump truck

The utility model relates to a wet and slippery pavement braking system for a mining dump truck, belongs to the technical field of control systems for mining dump trucks, and mainly solves the problem of high probability of tire locking caused when a conventional mining dump truck is braked by foot stepping on a wet and slippery pavement. The wet and slippery pavement braking system for the mining dump truck is mainly characterized by comprising a mining dump truck braking system composed of a front axle controller, a pedal valve, a rear axle valve controller, a rear axle electromagnetic proportion brake valve, a rear axle relay valve, a front axle relay valve and a front axle electromagnetic proportion brake valve; the front axle electromagnetic proportion brake valve is a current-mode proportion brake valve; the two ends of the front axle electromagnetic proportion brake valve are connected in parallel with an adjustable resistor and a wet and slippery pavement select switch which are connected in series, t
