Abstract: High-quality and fast execution of mine workings imposes high requirements on the reliability, productivity and a number of other criteria on the tunneling and cleaning equipment. In turn, coal and rock massifs require timely inspections and monitoring of their condition. Continuity and high accuracy of monitoring the condition of the coal and rock massif will allow predicting and avoiding dangerous consequences caused by unexpected roof collapses. These factors and the ever-increasing volumes of cleaning work require optimal methods of diagnostics and monitoring of the roof condition, which have such important properties as high reliability of results, convenience and efficiency of work, as well as minimization of labor and economic costs for their implementation, safety of implementation. One of the options for solving this problem is the development and implementation of sensors for determining displacements in the roof. The development team working on the project is considering several different options for the design of a potential displacement sensor in the roof. Several options based on different physical effects for detecting displacements, transmitting, and storing the data have been selected for experimental research. This article will explore the initial experimental and theoretical findings in this area. It is planned to continue with a series of articles that will provide insights into the development of this topic, including the practical implementation and testing of prototypes of both the sensors themselves and their integration with data processing, transmission, interpretation, and visualization systems. In the future, a special task will be to consider the specifics of integrating the received data with the security and alerting system of coal enterprises in the context of current requirements for industrial safety and a multifunctional security system. It is noteworthy that despite the presence of offers on the market for certain sensor designs, they have not generated significant interest in implementation due to a number of significant technical and economic shortcomings that should be avoided when implementing the new system.
