Abstract: The article discusses specific features of processing carbonate rocks into crushed stone of various fractions. High level of mineral raw materials lost during mining and processing requires implementation of more complex production processes. At the same time, improving the quality of finished products is a pressing task for companies in the construction industry. Improving technologies for developing carbonate deposits involves implementing selective mining of heterogenous rocks, reducing the yield of crushing fines, and expanding the range of manufactured products. An analysis of the technological process for converting carbonate rocks into crushed stone was carried out, and a software suite for modeling rock mass processing operations was reviewed. A process flowsheet for carbonate rocks from the Melekhovo-Fedotovskoye deposit was reproduced within this dedicated software suite, and simulation modeling was performed for various equipment layout configurations. The information obtained can serve as a basis for organizing in-pit haulage at the mine, as well as for performing technical and economic calculations for new construction or technical upgrade of the processing facilities.
