Incidents of industrial and environmental safety violation modeling in the chain of technological cycles of a mining enterprise

The impact of incidents of industrial and environmental safety violation on the cost and time parameters of technological cycles implementation at a mining enterprise is considered. A formal model for the detection and effective enterprise development has been developed based on the determination of parameters that cause emergency disruptions to production processes and the reasons for the safety of mining operations in the chain of the enterprise technological cycles. The laws of distribution of time parameters of the production process and probabilistic analysis of the network model are proposed to increase the reliability of the implementation of the production program. Formulas for calendar plan parameters optimizing for conducting mining operations in terms of time and costs with a limited total consumption of homogeneous production resources, taking into account the occurrence of various types of incidents of violation of industrial and environmental safety of mining operation are suggested.
