This application relates to the field of underground transportation in coal mines and discloses a method for intercepting runaway speeding vehicles underground. The method includes: acquiring the vehicle speed and a preset speed threshold; triggering a hook to pop out downwards when the vehicle exceeds the speed limit; the hook inserts into a groove in the bottom plate and moves forward with the vehicle, physically connecting with an arresting cable in the shallow groove; the arresting cable, under traction, causes an upper sliding magnet to slide within a steel groove, generating friction and forming a first-stage braking force; the upper sliding magnet approaches a lower fixed magnet, generating a magnetic repulsion force of the same pole, which, combined with the friction force, forms a second-stage braking force until the vehicle stops; finally, the connection is released and the system is reset. This application achieves smooth vehicle interception through the two-stage superposition of friction and nonlinear magnetic repulsion, avoiding rigid impact; a power-off trigger mechanism ensures reliable interception when the vehicle is damaged due to power failure; and the reserved redundant rope segment at the end of the arresting cable compensates for tensile deformation, preventing cable overload and breakage.
