The article shows the importance of mathematical models for developing students' practical skills in prospecting, sampling and exploration of minerals.The main types of mathematical models of geological objects used for solving educational problems are considered, using the example of two geological objects - bauxite-bearing and mica-bearing territories. Automated training systems created on the basis of these models and their role in the educational process are characterized.

Bauxite deposits of the Turgai trough, which are one of the raw material bases of the alumina and aluminum industry of the USSR, are known since 1931. These deposits belong to the platform karst and karst-erosion ...

Deposits of refractory clays in the northwestern part of Donbass are confined to the sandy-clay strata of the Poltava Formation of the Lower Neogene. Refractory clays lie on the Upper Paleogene sandy sediments of the Kharkov and Berek formations, they are covered by sands of the Poltava Formation or mottled clays of the Lower Neogene horizon of mottled clays, less often by Quaternary loams. ...

The Pikalevskoye deposit of fluxing limestone (Leningrad Region) is located within the so-called Carboniferous plateau. The productive strata of the deposit is represented by organogenic, crystalline and dolomitic limestones and dolomites of the Tarussky and Venyevsky horizons of the Visean Stage, which in the western part are overlain by Quaternary moraine and lake-glacial deposits with a thickness of 6 to 30 m, and in the east also by terrigenous carbonate rocks of the Steshevsky horizon of the Visean Stage and dolomites of the Protvino horizon of the Namurian Stage.

Geological and industrial classification of dolomite deposits, reflecting both the peculiarities of their geological structure and the peculiarities of their exploration and exploitation, plays an important role in the selection of the system of exploration and evaluation of deposits. However, the existing classifications of carbonate rock deposits do not fully solve these problems ...

Widespread development of the oxygen-converter method of steel production puts forward before the refractory industry the task of providing converter shops with cheap high-strength refractories made from widely available raw materials. In domestic steel converters, the best resistance has a lining made of fired periclase-spinelide brick made of fired magnesite and chromite ore. However, the experience of foreign countries using the oxygen-converter method of steel production shows that the greatest durability of lining and high economic effect are achieved with non-fired dolomite and dolomitomagnesite refractories made of burnt dolomite (or dolomitized magnesite) on a binder of coal tar, pitch or tar. Since resin dolomite refractories are cheaper than periclazspinelidnyh and have a higher resistance, they are accepted as lining material and for the designed in the USSR oxygen-converter shops ...
