METHODOLOGY FOR IMPROVING ENVIRONMENTAL FRIENDLINESS AND ENERGY EFFICIENCY IN OPEN PIT MINING OF MINERAL DEPOSITS

The article is devoted to the actual topic, which combines problematic issues of energy efficiency and low-carbon development of mining production with the open-pit method of development of solid mineral deposits. It touches upon the methodological aspects of improving the environmental friendliness and energy efficiency of the main production processes on the example of one of the mining enterprises in Kazakhstan. As a description of methods and approaches is presented an algorithm for accounting energy consumption and environmental emissions in the functioning of geotechnological complex with the use of road transport of extracted rock mass, depending on the technical condition, organization and operating conditions of the main mining and transport equipment in the course of simulation modeling. The list of output information on ecological emissions, as well as diagrams of energy consumption and volumes of ecological emissions by sections of the highway, depending on the quality of the road surface, the number and intensity of vehicles passing along them, is demonstrated in the form of an output table. Attention is also paid to the use of vehicles with electric and diesel engines. Based on the results of the study, an assessment of the effectiveness of taking a set of measures aimed at improving the engergo- and environmental efficiency of geotechnological complexes is presented.
