Indicators of the emergence of hazardous production situations in the integrated monitoring data of the state of mining operations

Abstract

Research relevance. Studies of the causes and mechanism of hazardous production situations origin and development at coal mining enterprises have shown that their development is most often due to organizational factors, and the prerequisites for their occurrence are associated, to a greater extent, with process flow factors of mining operations, including design decisions. For this reason, it became necessary to establish specific process flow factors that are prerequisites for the emergence of hazardous production situations at a coal pit. Research objective is to establish the factors of hazardous production situations occurrence; to identify and justify indicators of hazardous production situations origin, obtained based on an assessment of the general state of mining, to take into account appropriate scenarios for preventing or avoiding the hazardous production situations in the course of development; to diagnose early signs of their occurrence and eliminate the causes of their development. Methods of research. The state of mining in the coal pit and operations on production safety were assessed from the perspective of hazardous production situations origin and development and was carried out during the process audit. Indicators of the state of the deep pit working area were formed based on the analysis of data from geographic information monitoring of mining, safety rules, as well as process flow diagrams of mining operations. Results. Based on the results of the process audit of the state of mining operations, the factors that are prerequisites for the development of hazardous production situations are determined. They became the basis for the selection of process flow and organizational indicators of hazardous production situations occurrence. The conditions for hazardous production situations occurrence are defined, depending on the presence of objective natural, process flow and organizational factors affecting the safety of work. Conclusions. Open-pit coal mining is naturally accompanied by the emergence and development of hazardous production situations. It is proposed to monitor the prerequisites of hazardous production situations by process flow and organizational indicators in order to make adequate management decisions to prevent the occurrence of hazardous incidents.
