Моделирование отработки запасов рудного месторождения в условиях Крайнего Севера

Abstract

The article presents a solution to the practical problem of ore deposit opening-up and mining. A digital geological model of the ore deposit was created in the mining and geological information system (MGIS) MINEFRAME. The authors carried out an automated analysis of mining and geological conditions of the deposit and calculated balance and off-balance reserves. Parameters and boundaries of a protective pillar under protected surface water objects were determined; its digital model was created and ore reserves within its limits were calculated.The annual production capacity and the mining period of the first stage of underground mining of deposit area were calculated. Based on the analysis of the thickness of the overlying rocks above the ore deposit and surface, rational locations for the main underground mine openings on the surface were identified. The authors created a digital scheme of opening-up and reserves preparation for stope excavation in MGIS MINEFRAME. The construction volume of mine workings was defined using an automated mining planning module. To ensure safe and comfortable environment when conducting underground mining under the Far North conditions with caving of ore and host rocks the authors determined the need to create a safety and thermal insulating pillar.
