Rock burst prevention and control early warning system and method based on fault penetrating anchor cable stress change

The invention provides a rock burst prevention and control early warning system and method based on fault penetrating anchor cable stress change, and relates to the technical field of rock burst early warning, the system comprises an anchor cable and a data monitoring acquisition instrument, one end of the anchor cable is arranged in a rock mass around a chamber in a penetrating mode, and the anchor cable comprises an internal supporting piece, a strain gauge, an elastic piece, an outer layer protection pipe and an electric wire. A plurality of anchor cables are arranged at the section of the chamber and can penetrate through a fault plane existing in a rock mass, when rock displacement occurs at the fault plane, the anchor cables are bent and deformed, at the moment, elastic pieces at the deformed positions of the anchor cables get close to strain gauges and extrude the strain gauges, and the strain gauges on the anchor cables send data back to a data monitoring and collecting instrument; the actual stress v
