FBG Sensing Technology for the Roadway Strain Monitoring in the Coal Industry
In the coal industry, roadways are essential for transporting equipment, materials, and personnel. These roadways are subjected to significant stresses and strains due to the weight of the equipment and materials, as well as the movement of vehicles. Monitoring roadway strain is critical for ensuring the safety of workers and preventing equipment damage.
Fiber grating sensing technology has become an increasingly important tool in the coal industry for monitoring the strain on roadways. This technology utilizes optical fibers that contain periodic structures, known as gratings, which reflect light of specific wavelengths. By measuring changes in the reflected light, it is possible to detect strain on the roadway in real-time. 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 help to monitor the roadway strain in the coal 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.

Demand Analysis for Roadway Strain Monitoring in the Coal Industry:
The coal industry has a high demand for roadway strain monitoring due to the critical role of roadways in mining operations. Monitoring roadway strain in real-time can help prevent equipment damage and ensure the safety of workers. However, traditional strain monitoring methods, such as strain gauges, can be difficult to install and maintain in the harsh mining environment.
Why Monitor Roadway Strain is Needed：
Monitoring roadway strain can help identify potential roadway failures and prevent accidents. In addition, it can help optimize mining operations by identifying areas of high strain and potential equipment damage.
Difficulties in Monitoring Roadway Strain：
Monitoring roadway strain in the coal industry can be challenging due to the harsh mining environment, which can cause damage to traditional strain gauges. In addition, the installation and maintenance of strain gauges can be time-consuming and expensive.
What Problems can be Solved by FBG Sensing Technology:
Fiber grating sensing technology can help solve some of the challenges associated with traditional strain monitoring methods. Fiber Bragg grating sensors are small and lightweight, making them easy to install and maintain. In addition, they are highly sensitive and can detect small changes in strain, allowing for real-time monitoring of roadway strain.
