DIGITAL SIMULATION OF OPEN-PIT MINING ORGANISATION SYSTEM

The process of digitalization in Ukraine is slow, so studying the state of digitalization of the mining industry is a very relevant issue and will help increase the competitiveness and efficiency of enterprises, which is important for the development of the national economy. The research aims to the state of mining industry digitalization in Ukraine, develop an effective methodology for volumetric modelling of open-pit mining enterprises, and implement an effective digital modelling system. Research methods include analysis of literature sources, factor and situational analysis, comparative economic analysis, system analysis of software, and digital modelling of the enterprise system. Mining and geological data processing and mathematical modelling were used to obtain the following results: the data were digitized, a polygon database was built, the area of the ore body was determined, the cut planes were constructed and drilling and blasting operations were modelled. The creation of a frame and block model of the deposit is investigated and a methodology for block modelling of mineral quality is proposed, which will allow for high-reliability zoning of technological types of minerals in the quarry. Implementing an integrated software system for the digital modelling of the deposit will enable efficient visualization of the distribution of useful components, resulting in improved competitiveness and modernized planning and management of mining processes. The proposed block modelling methodology for the open pit space further enhances the practical value of the study.
