In this study, the authors have continued investigating the tasks of the joint application of the Gauss-Laplasse and B (beta) distributions to describe the disintegration of minerals of poly-mineral ores, which is associated with the mineral grains liberation, i.e., the release of mono-mineral particles from the aggregates with other minerals. The article presents an approach for a simulation modeling algorithm for disintegration operations of mineral particles in technological flowsheets of mineral processing. Us...

In modern mining a tendency is observed to extend underground development of near open-pit reserves in thick ore deposits because of increase of open-pits ready to complete open mining operations or technical elimination. Researchers of Mining Institute KSC RAS have established that when developing the near open-pit reserves by mining systems of ore and country rock caving, the parameters of ore excavation and mining safety increase due to controlling ore drawing and constructing a thermal insulating layer. The ma...
