The invention discloses an anti-overspeed brake control system for a mining vehicle engine, which is characterized in that a CAN (Controller Area Network) module acquires and outputs a vehicle speed signal and an engine rotating speed signal; the ADC module obtains a brake pedal opening signal, an accelerator pedal opening signal, a vehicle attitude sensor signal and a vehicle load sensor signal, and outputs the signals after analog-to-digital conversion; the ROM program memory module stores a control program algorithm; the RAM data memory module obtains signals output by the CAN module and the ADC module and stores the signals as to-be-processed signal data; the CPU calls a control program algorithm to process to-be-processed signal data when the system is started, determines a braking demand and outputs the braking demand to the CAN module; the CANs module outputs an instruction according to the braking requirement to instruct a corresponding controller to work so as to control the rotating speed of an engine; the function switch can switch on and off the system; the power module provides power voltage. According to the invention, the combination of retarder braking, engine braking and drive-by-wire service braking can be adopted according to the working condition of the vehicle in the mining area to prevent overspeed.
