When a vehicle passes through a region where an electromagnetic vehicle stopping mechanism is located in use, the resistance of a resistor 16 is increased, an electromagnetic braking vehicle 14 moves in (near) a coil 17 to cut magnetic force lines, so that generated electric energy is consumed on the resistor 16, the electric energy is generated by cutting the magnetic force lines, meanwhile, a magnetic field can generate acting force opposite to the moving direction of the electromagnetic braking vehicle 14, the faster the speed is, the larger the reaction is, the speed of the vehicle can be reduced rapidly, and the purpose of stopping the vehicle is achieved.

The faster the electromagnetic braking vehicle 14 moves, the speed measuring probe 9 detects and transmits detected data to the main control computer, the main control computer can master the moving speed of the electromagnetic braking vehicle 14 in real time, the resistance value of the adjusting resistor 16 can adjust the resistance of the advancing direction of the electromagnetic braking vehicle 14 in real time, and the resistance can be accurately adjusted. If the electromagnetic braking fails, the main control machine can remotely control the vehicle blocking frame 54 to carry out secondary vehicle blocking, and the two measures are mutually backed up, so that the absolute safety of the vehicle in the mine inclined shaft can be ensured (the electromagnetic braking vehicle blocking actually uses Lenz's law, namely, induced current has such a direction that the magnetic field of the induced current always obstructs the change of magnetic flux causing the induced current, and the Lenz's law can also be expressed as that the effect of the induced current always resists the reason for causing the induced current).
