Development of the System for Continuous Automatic Control of Dustiness and Dust Deposits Intensity as a Subsystem of the Multifunctional Safety System of a Coal Mine



Annotation:

In connection with the growth of coal production and the load on mining enterprises, as well as the modernization of the main mining industries, the urgent task is to improve the level of industrial and occupational safety, which is impossible without improving the system for monitoring safety parameters in the automated mode. The control of dust and explosion safety of the mine workings in accordance with the safety requirements is conducted with special devices or other continuous equipment, in accordance with paragraph 22 of the Federal rules and regulations in the field of industrial safety «Safety rules in the coal mines». Within the framework of the article, the development of a new device for monitoring dust content and dust deposition is considered — a system for continuous automatic monitoring of dust content and intensity of dust deposition. Investigations of the regularities of the process of dust deposition of hovering coal dust were carried out depending on various factors affecting the distribution of dust along the network of the mine workings, namely, the grade composition of coal, a set of technological parameters and the parameters of atmospheric indicators. Performed complex of the laboratory and mine research of the innovation system confirmed the correctness of the developed physical model for assessing the state of dust and explosion safety in the coal mining. The system of continuous automatic monitoring of the dust content and the intensity of dust deposition meets the modern requirements of the Federal rules and regulations in the field of industrial safety in terms of automatic continuous measurement of dust concentration in the mine atmosphere, and (or) dust deposition, telemetry, remote signaling when the threshold values of dust deposition concentrations are exceeded, and in case of failure of the dust sensor, as well as local light and (or) sound alarms, automatic transmission of data on exceeding the threshold values of dust concentrations in the mine atmosphere, and (or) dust deposits in real time via communication channels to the coal mining organization.
