Rationing the level of safety of work shifts is a multifaceted problem, since it must be decided on the basis of technical, economic, moral and socio-political aspects. The requirements of the risk level, arbitrarily close to zero or zero, seem unrealistic, since it requires infinitely high costs when creating a technological facility and a mine as a whole. In addition, when distributing investments, it is necessary to take into account not only the costs of ensuring safety, but also ensuring the reliability and targeted efficiency of the technological site and the mine as a whole. All these components are quite rigidly interconnected. When varying the design characteristics of reliability and target efficiency, secondary changes in the technological parameters of the object can be observed. Thus, an increase in the reliability of process equipment and control systems due to redundancy causes changes in the design balance of costs for operating the facility, that is, an event aimed at improving safety can ultimately lead to its reduction
