Provided are an NPR anchor rod monitoring and control system and method for a rock slope collapse disaster. The system comprises a flexible anchor net, an NPR anchor rod, a monitoring unit, a base station and a monitoring center. The flexible anchor net is laid on the surface of a jointed rock mass. The NPR anchor rod is used for reinforcing the jointed rock mass and a stable rock mass. The monitoring unit is installed on the NPR anchor rod. The base station is in communication connection with the monitoring unit. The monitoring center is in communication connection with the base station. When the rock mass collapses, the NPR anchor rod is greatly deformed, absorbing a large amount of energy, and loose gravel may be controlled by means of the flexible anchor net having high-strength and high-toughness. For a large-scale rock collapse, the present invention allows for effective control and delay of collapse disaster time, such that more time is provided for personnel and property evacuation. For a small-scale rock collapse, the present invention allows for the rock mass collapse to be controlled, and a disaster caused by falling rock mass may be effectively avoided.
