Methodology of creation and development of information systems for technological safety of mining facilities

Purpose. To develop methodological approaches to the process of informatization of technological security (TS) and to propose a project of step-by-step development of the architecture of information system (IS) of TS, which will contribute to effective integration of digital and mining technologies. To develop a mathematical model for finding the number of sensors required for probabilistic assessment of the concentration gradients of hazardous gases. Methodology. General and special methods of knowledge are used: structural analysis – to establish the structure and tasks of IS of TS; logical generalization – for formation of methodological system of directions of TS information measures; system analysis – to establish synergistic effect of complex implementation of the indicated directions; scientific abstraction – for development of a project for IS architecture derivation; mathematical formalization – for development of mathematical model for estimating gradients of concentration gases and the number of sensors. Findings. A project for the phased development of IS architecture of mining facilities based on the implementation of diffusion principle is developed, which will allow solving a complex of issues: integrated monitoring of danger of gas environment of underground structure for detection of gas traps and permanent determination of concentration gradients of hazardous gases, implementation of intelligent safety loops using analytical resources of technological mining process. A methodological system of directions for diffusion implementation of TS information measures is formed. The use of the method of system analysis made it possible to point out the synergistic effect of the complex implementation of the directions of implementation of TS information measures. Originality. A project for the phased development of the information system architecture of the technological safety of mining enterprises has been developed. A mathematical model has been developed to estimate the concentration gradients of hazardous gases and the number of sensors to ensure the appropriate level of probability of finding a sensor in each cell of the underground mine. Practical value. The methodological approach makes it possible to form an IS that implements a comprehensive approach to ensuring the appropriate level of technological safety of mining facilities.
