GNSS-Enabled Real-time Monitoring for Mine Slope Safety

I. Scheme Background

During the process of mine exploitation, the stability of slopes is of crucial importance. Unstable slopes may lead to safety accidents such as landslides and collapses, posing a serious threat to human lives and property. The GNSS satellite navigation system has the advantages of high-precision positioning and real-time monitoring and can be effectively applied to mine slope monitoring.

II. Monitoring Objectives

Real-time monitoring of the displacement and deformation of the slope, including horizontal displacement and vertical displacement.
Monitoring the change in the slope's inclination angle to timely discover potential landslide risks.
Monitoring parameters such as the stress and pressure of the slope to assess its stability.

III. Composition of the Monitoring System

GNSS monitoring stations: Install GNSS monitoring stations at key positions on the slope to receive GNSS satellite signals and measure the position coordinates of the monitoring points in real time.
Data transmission system: Transmit the data collected by the monitoring stations to the monitoring center through wired or wireless means.
Monitoring center: Equipped with professional monitoring software to process, analyze, and display the data and issue early warning information in a timely manner.

IV. Advantage Analysis of the GNSS Slope Monitoring System

First, the GNSS system can provide centimeter-level or even millimeter-level positioning accuracy, which can accurately monitor the slight displacement and deformation of the slope and provide reliable data for early warning.
Second, it can monitor the slope status in real time around the clock, unaffected by factors such as weather and time, and can timely discover potential dangers, gaining valuable time for emergency handling.

V. Early Warning Mechanism

Set early warning thresholds: Set reasonable early warning thresholds for displacement, deformation, stress, etc. according to the actual situation of the mine slope.
Hierarchical early warning: Divide the early warning levels into different grades, such as yellow warning, orange warning, and red warning, and take corresponding countermeasures respectively.
Early warning notification: Notify mine managers and relevant departments in a timely manner through SMS, email, sound and light alarms, etc.

VI. Summary

By implementing the mine GNSS slope monitoring scheme, the stability of the mine slope can be mastered in real time, potential safety hazards can be discovered in a timely manner, providing strong support for the safe production of the mine.
