Prevention of air pollution during openpit mining of ore deposits

The article contains information about the prevention of air pollution during open-pit mining of ore deposits. The assessment of the relevance of the problem of atmospheric pollution is given. A system of minimizing atmospheric pollution by complying with the restriction criteria is proposed. A mathematical model is proposed, the objective function of which is the minimum of dust emission, and the limiting conditions are variable factors. A reference is given on the development of the fundamentals of ecology of mining regions. Approaches to the formulation of research technologies for minimizing the volume of dust and establishing system connections and patterns in the process of controlling the state of the atmosphere are formulated. The typification of dust and sources of dust formation is proposed. The surroundings of the quarry were ranked into zones according to the danger of dust pollution. The intensity of dust emission during the implementation of technological processes is investigated. The results of the study of the sources of dust formation and concentration in the quarry atmosphere in comparison with the analogs are presented. The assessment of dust binding technologies is given. An integral indicator of the state of the atmosphere of the quarry is proposed. An algorithm for controlling the state of the atmosphere, including the stages of pollution risk management, has been developed. The results of modeling the ways of solving the problem by the method of full search are presented. It is established that the effectiveness of measures to minimize dust pollution is described by the function. Each of the dusting objects has an individual characteristic, which can be quickly replenished. The system for predicting the magnitude of dust emissions includes the development of an output function, a model of technological processes and a transition function. The proposed system for monitoring the state of the atmosphere provides an increase in the effectiveness of the atmospheric protection strategy.
