FBG Sensing Technology for the Geotechnical Monitoring
The mining industry is subject to numerous geotechnical challenges that can pose significant safety risks and threaten the stability of mining operations. Geotechnical monitoring is essential to ensure the safety and stability of mining infrastructure, including tunnels, shafts, and underground chambers. Fiber grating sensing technology provides a powerful tool for geotechnical monitoring in the mining industry, allowing for real-time, accurate monitoring of ground motion, subsidence, and geotechnical stability. In this article, we will discuss the problems that fiber grating sensing technology can solve, and how Beijing Dacheng Yongsheng Technology Co., Ltd.(short for DCYS ) can support the geotechnical monitoring in the mining industry.
Fiber Bragg Grating Sensing Principle：
Fiber Bragg gratings (FBGs) are periodic structures that are inscribed in the core of an optical fiber. These structures reflect a specific wavelength of light that is determined by the periodicity of the grating. When the grating is subjected to mechanical or thermal strain, the reflected wavelength changes in a predictable manner. By monitoring the reflected wavelength, changes in strain, temperature, and other parameters can be detected. FBG sensors can be used to monitor a wide range of parameters, including strain, stress, temperature, and vibration.

Needs Analysis for Geotechnical Monitoring in the Mining Industry:
Mining operations are inherently hazardous, with risks posed by unstable geological formations, water inundation, and equipment failures. Geotechnical monitoring is essential to mitigate these risks and ensure the safety of personnel and infrastructure. Ground motion, subsidence, and geotechnical stability are critical parameters that must be monitored to ensure the safety and stability of mining operations.
Why Monitoring for Ground Motion, Subsidence, and Geotechnical Stability is Needed:
Mining operations can significantly impact the surrounding geology, resulting in ground motion, subsidence, and changes in geotechnical stability. Monitoring these parameters is essential to identify potential risks, such as sinkholes or landslides, and take appropriate action to mitigate them. Ground motion can also impact the performance of mining equipment, causing damage and increasing maintenance costs.
Difficulties in Monitoring Ground Motion, Subsidence, and Geotechnical Stability:
Traditional monitoring techniques for ground motion, subsidence, and geotechnical stability often rely on a network of point sensors, which can be costly and time-consuming to install and maintain. Additionally, traditional sensors may not provide accurate data on the spatial and temporal variations of these parameters, making it difficult to identify potential risks and take appropriate action.
What Problems can be Solved by FBG Sensing Technology:
Fiber grating sensing technology provides a powerful solution to the challenges of geotechnical monitoring in the mining industry. FBG sensors can be embedded in the ground or attached to structures such as tunnels or shafts, providing real-time, accurate monitoring of ground motion, subsidence, and geotechnical stability. Fiber grating sensors are also resistant to electromagnetic interference, making them ideal for use in mining environments.
