The invention discloses a quarrying field safety monitoring system and method. The system comprises a control background and a landslide detection subsystem, the control background is in communicationconnection with the landslide detection subsystem and is used for receiving the detection data and carrying out prediction and early warning on the disaster sign, the landslide detection subsystem comprises a quarrying field body landslide module and a waste dump landslide module, the quarrying field body landslide module includes a plurality of sensor detection units arranged on the side slope,the waste dump landslide module comprises a monitoring unit for detecting the moving amplitude of the waste soil. The system has the advantages that the rock condition of the quarrying field body andthe waste soil condition of the waste dump are detected through the landslide detection subsystem, and the disaster sign analysis is carried out through the control background, so that the possible danger can be determined, and the dangerous case content and the dangerous case suspected coordinates are sent to an alarm module in time, and the alarm module is used for informing an operator in the vicinity of the dangerous case suspected coordinates to timely evacuate or strengthen the side slope monitoring and management, so that problems can be found in time and preventive measures can be taken.
