Abstract

Currently, there is a large amount of literature on the safety of power electrical circuits, however, they completely lack the safety issues of using measuring circuits in coal mines. And measuring circuits are an important integral part of diagnostics and information content of mining equipment control systems. The article clearly shows the solution to the problem of the safety of using measuring circuits in coal mines. The admissible parameters are revealed and the relationships of these parameters are found, which ensure the intrinsic safety of the measuring circuits. A tubeless technique for assessing the intrinsic safety of measuring circuits is proposed. An example of the application of the developed methodology is considered on the example of a specific control sensor of the 4201 DST-10 type of the mobile control system of the MAK-2 type. The introduction of the developed methodology at two coal mines in Ukraine and approbation at five foreign conferences is shown.
