Dangerous rock mass collapse real-time early warning system and method based on multiple monitoring indexes

Abstract

The invention discloses a dangerous rock mass collapse real-time early warning system and method based on multiple monitoring indexes. The system comprises a monitoring system, a measurement and control center, and an early warning analysis system, the monitoring system comprises a laser vibration meter, an information acquisition system, and an automatic meteorological station, and the laser vibration meter is used for measuring the vibration frequency of a dangerous rock mass; the information acquisition system and the automatic meteorological station are used for measuring parameter information of the dangerous rock mass; the measurement and control center stores, organizes and processes the information and transmits a result to the early warning analysis system; the early warning analysis system comprises an early warning threshold value adjustment and comparison module, an alarm and an automatic roadblock, and the early warning threshold value adjustment and comparison module dynamically analyzes a static index displacement early warning threshold value and compares the static index displacement early warning threshold value with an actually measured displacement value; when the measured value is larger than the early warning threshold value, the alarm and the automatic roadblock are started. A dynamic index, a static index and an environment quantity index are comprehensively monitored and evaluated, the displacement index threshold value can be analyzed and adjusted through returned information, and the monitoring accuracy is improved.

Description

technical field [0001] The invention belongs to the field of geological disaster monitoring and early warning, in particular to a real-time early warning system and method for dangerous rock mass collapse based on multiple monitoring indicators. Background technique [0002] Dangerous rock collapse is a type of geological disaster in mountainous areas, a geological phenomenon caused by natural dynamics, and an engineering geological change process of natural hillsides due to human activities. The collapse of dangerous rocks may bury roads and railways, bringing major safety hazards and losses to transportation, and it can also change the local terrain and destroy artificial buildings and their environment, endangering people's lives and property. Therefore, it is necessary to monitor and warn the deformation of dangerous rock mass collapse in order to reduce the loss caused by dangerous rock mass collapse. [0003] The current monitoring technology and methods of collapse d...

AI Technical Summary

Problems solved by technology

The inventor found that due to the complexity, randomness, and diversity of influencing factors of the collapse disaster itself, it is difficult to judge the main factors causing the collapse. The previous monitoring technology considered fewer factors, and the monitoring indicators were relatively single, which could not be reasonably evaluated. The trend of collapse

In addition, after receiving the warning of collapse, mining often fails to notify passing vehicles in time, and the practice of manually setting up roadblocks to prevent vehicles from entering the dangerous area is not timely enough
