I. Mine construction monitoring
(1) Monitoring of relative displacement of surrounding rock surface
1. Convergence measurement: It measures the relative deformation and deformation law between two points on the surface of the roadway.
2. Conductor measurement and elevation measurement: measure the absolute displacement of the surface of the surrounding rock.
(2) Deep surrounding rock displacement monitoring
1. Multi-point displacement meter measurement 2. Separator: monitor relative displacement.
(D) Loose circle monitoring: using ultrasonic wave speed and electromagnetic radar.
Second, open pit slope monitoring
(1) Basic requirements for monitoring:
Class I monitoring is a comprehensive, regular inspection of the overall slope.
Level II monitoring is the monitoring of unstable slopes.
Vibration monitoring: The rock's frequency and amplitude of sound emission will be significantly increased before rupture to predict the risk of landslide.
