Abstract.
This article is devoted to substantiation of basic algorithms for the information system which could provide prompt making of decisions on ensuring safety of underground mining jobs, which are of great importance for the job safety at the mining enterprises. The information safety system architecture and some basic algorithms was developed. The system differs by its methods for prompt predicting and assessing of different scenarios of geomechanical process development, and which includes the following subsystems: a basic client-server subsystem with functions of interaction between the personnel and management of the enterprise; a reference and information subsystem, which supports a decision making process, accumulates data and analyzes technical documentation; a subsystem for analyzing the job safety by geomechanical factors and for assessing of the "support-rocks" system state basing on the risk criteria and mathematical fuzzy logics. Two integral indicators of safety are formed. The first indicator is used to control entering of the control object to the emergency mode and to determine a factor, which requires urgent interruption, and the second indicator is used for the total assessment of the object current state. To validate the risk criteria for assessing the job safety with taking into account geomechanical factors, typical scenarios of distribution of zones with inelastic deformation and stress changes in the rock mass are identified. With the help of method of mathematical modeling, the geomechanical situational models were calculated, which assumed use of different types of supports, increase of load on the "support-rocks” system, and changing conditions of the rocks bedding and water intrusion. Algorithms were tested on example of typical organizational structure of the mines and approved in the production conditions. The results showed that the information system improved rate of the underground mining jobs safety through support of decision-making process at various levels, more detailed data processing on the base of mathematical models and criteria assessing rate of danger for the control object by methods fuzzy logics. “The Methodical Recommendations on How to Use the Information System for Ensuring the Underground Mining Jobs Safety on the Basis of Geomechanical State of the Rock Massif” were developed and implemented.
Keywords: underground mining, stress-strain state of rocks, safety information system.
