This article discusses one of the methods of monitoring the state of the geotechnical state of mining in real time. One of the problems of operating reference stations is the constant inspection by the marker services for the technical condition of the mine workings. The authors describe the developed fiber-optic monitoring sensor capable of monitoring and warning about abnormal situations of the geotechnical state of underground mining. A detailed analysis of the use of such devices and scientific achievements in mining enterprises is presented. Fiber-optic sensor design. A fiber-optic sensor for the displacement of rocks of the mine workings and a measurement system were developed. The work uses a unique method for controlling changes in the properties of a light wave passing through an optical fiber, which significantly reduces the cost of measuring a single point. The research included monitoring the condition of the mining workings of the Tentekskaya mine. According to the results of the research, a graph of the dependence of optical losses on the displacement value was obtained, an automated approximation of the data was carried out, all changes are recorded by the hardware and software control complex and displayed on the screen. The developed fiber-optic displacement sensor together with the hardware and software control complex have proven their operability and safety of operation in mining enterprises.
