Abstract

We focus on the working environment of the mine based on the fiber grating sensing theory because of its passive, high-sensitivity and small-sized fiber grating as the front-end sensing unit to realize the integration and miniaturization of mine sensors. The structure of the sensor has been designed and analyzed according to the differential compensation methods. The differential dynamic temperature compensation algorithm can effectively eliminate the influence of temperature on the pressure detection by using the temperature-strain cross-sensitivity of the fiber grating. The temperature sensitivity is 31pm/°C, and the pressure sensitivity is 298 pm/Mpa with optimization. It can well realize the accurate measurement of various environmental parameter information in the process of coal mining, and fully reflect the superiority of the fiber sensor in the application of the coal mine engineering.
