FBG Sensing Technology for the Strain Monitoring of Mining Machinery

The coal industry is one of the most important sectors in the global economy. The mining machinery used in the coal industry plays a crucial role in the extraction and transportation of coal. The proper functioning of mining machinery is essential for ensuring the safety of workers and maximizing efficiency. Strain monitoring is an important aspect of maintaining the health and safety of mining machinery. Fiber grating sensing technology has emerged as a reliable and effective method for monitoring the strain of mining machinery in the coal 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 help to do strain monitoring of mining machinery 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.

Application of Mining Machinery in the Coal Industry:

The coal industry uses a variety of mining machinery, including continuous miners, longwall shearers, and shuttle cars. Continuous miners are used for cutting coal from the face of the mine, while longwall shearers are used for extracting large blocks of coal. Shuttle cars are used for transporting coal from the mining face to the surface.

Why the Strain Monitoring of Mining Machinery is Needed:

The strain on mining machinery can lead to failure and downtime, which can cause safety hazards and significant financial losses. Monitoring the strain of mining machinery can help to detect potential failures before they occur and allow for preventative maintenance. This can reduce downtime, increase productivity, and improve safety.

Difficulties in the Strain Monitoring of Mining Machinery:

Monitoring the strain of mining machinery in the coal industry is challenging due to the harsh operating environment. The mining machinery is subject to vibration, shock, and extreme temperatures, which can affect the accuracy and reliability of strain measurements. Additionally, mining machinery is often located in remote areas, making it difficult to access for maintenance and repair.

What Problems can be Solved by FBG Sensing Technology:

Fiber grating sensing technology can solve many of the problems associated with monitoring the strain of mining machinery in the coal industry. Fiber Bragg grating sensors are small, lightweight, and can be installed in harsh environments. They are also immune to electromagnetic interference, making them ideal for use in mining machinery. By using fiber grating sensing technology, mining companies can detect potential failures before they occur and take preventative action. This can improve safety, reduce downtime, and increase productivity.
