Abstract: In this paper, a conceptual solution for the stability management system of a mining engineering system is proposed based on a block of accounting for input parameters and system response parameters. One of the important structural subsystems is the mining condition monitoring system. In turn, any system should be based on key components that have constructive ease of manufacture, reliable operation and a rational operating scheme. Such a component for the underground mining condition monitoring system is the roof displacement sensor, which implements two levels of control. This study is devoted to the study of the design and technological parameters of a two-level roof displacement sensor (DSC-2). The appearance of the sensor housing, the layout of the internal components, the principle of operation and mounting options to the roof are presented. Primary capacitive type converters have been developed, which have the highest resource and noise immunity, which is especially important for coal mines. Signal level converters are considered and an electrical schematic diagram of the level converters and a general block diagram of the controller are developed. The introduction of roof displacement sensors into a comprehensive multifunctional mining safety system, within the framework of the subsystem for monitoring the condition of mining workings, will allow for a better understanding of the processes occurring with the rock mass. The results of the GPR inspection of the roof with characteristic patterns of detected and predicted violations are presented. The installation locations of roof displacement sensors are determined, among other things, by the results of a ground-penetrating radar survey and the identification of potentially dangerous areas. A further area of research is devoted to the development of software for continuous data accumulation and linking a network of similar sensors throughout the mine.
