Ecological impact on the environment of industrial mining of bentonite clays

Abstract

The object of the study is the Kattakurgan deposit of bentonite clays. During the implementation of the project, an environmental analysis of the design solution and the facility itself was carried out in terms of emissions, discharges, waste generation, and the degree of their impact on the environment was assessed. As a result of the environmental analysis, 6 sources of emission of pollutants, 4 unorganized sources of emissions of harmful substances of the area type were identified. The main source of air pollution is the bentonite clay quarry. In terms of ingredients, inorganic dusts account for the bulk of emissions. Analysis of the dispersion fields of pollutant emissions showed that the maximum ground-level concentrations of the considered harmful substances outside the enterprise do not exceed the values established by quotas. The water supply of the enterprise is carried out at the expense of imported water. Wastewater only includes domestic wastewater. An inventory of production and consumption wastes was carried out. It has been established that 5 types of waste are generated in the process of production activities of the deposit. The waste is non-toxic and low-hazard. Calculation of limits for disposal of production waste.
