METHODOLOGY FOR ASSESSING THE FRONTS OF MINING OPERATIONS OF DEEP QUARRIES BASED ON GGIS MODELING OF THE WORKING AREA

Abstract

The deterioration of mining-engineering and mining-geological conditions of mineral extraction, when mining operations decrease during the development of complex-structured deposits, requires the creation of innovative techniques that allow, based on the audit of the state of mining operations in the quarry, to ensure the planning of mining operations in the most cost-effective way. The article presents the basics of the developed methodology, which allows to automatically assessing the ratio of mining fronts and qualitative indicators of mineral reserves (MR) on the working horizons of the quarry. The purpose of the work is to reduce the labor-complexity and improve the quality of planning processes for mining. Better planning of mining operations, taking into account the quality of raw materials, allows to increase the degree of extraction of valuable components and the more comprehensive use of mineral resources. The proposed methodology is intended for automated planning of mining operations in the raw material quality management mode and allows to determine the reserves of mining production, to establish the predominant technological grade of ore raw materials in the analyzed areas of the deposit, and to choose a rational method of extraction of raw materials, taking into account its quality.
