FBG Sensing Technology for SHM of Mines in the Mining Industry
Structural health monitoring (SHM) is an essential process in the mining industry, which involves the use of sensors to monitor the structural integrity of mining equipment, tunnels, and shafts. Fiber grating sensing technology is one of the most advanced methods for SHM, providing accurate, real-time data on critical parameters such as temperature, strain, and deformation. This article will provide an overview of the principle of fiber grating sensing technology and its applications in SHM in the mining industry. 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 SHM 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.

Analysis of Needs for SHM of Mines in the Mining Industry:
The mining industry is a high-risk environment where structural failures can have severe consequences. The constant exposure of mining equipment, tunnels, and shafts to harsh conditions such as vibration, high pressure, and temperature fluctuations, can cause damage and reduce their structural integrity over time. As a result, SHM is critical to identify potential structural problems and to take preventative measures to ensure the safety of mining personnel and equipment.
Why SHM of Mines in the Mining Industry is Needed:
The monitoring of mining equipment, tunnels, and shafts can help identify potential structural failures before they occur, preventing downtime, equipment damage, and personnel injury. By implementing SHM, mining operators can increase the lifespan of their equipment and reduce maintenance costs. Additionally, SHM can improve the efficiency and productivity of mining operations, resulting in increased profitability.
Difficulties in SHM of Mines in the Mining Industry:
The mining industry presents several challenges to the implementation of SHM. The harsh mining environment can interfere with sensor data, causing inaccurate readings. Additionally, the remote locations of many mining sites can make it challenging to install and maintain sensors, increasing costs and logistical difficulties. Furthermore, the underground nature of mining operations can present safety hazards to personnel installing and maintaining the sensors.
What Problems can be Solved by FBG Sensing Technology:
Fiber grating sensing technology provides several advantages over other SHM methods, making it an excellent solution for the mining industry. Fiber optic sensors are immune to electromagnetic interference, making them ideal for use in high-vibration environments. Additionally, fiber optic sensors are small and lightweight, making them easy to install in remote locations. The real-time data provided by fiber grating sensing technology can detect subtle changes in the structural integrity of mining equipment, tunnels, and shafts, allowing for prompt maintenance and repair.
