Radioactive waste received by manufacture of electric power requires  a  highly reliable burial place. One of the most perspective types of storehouses is underground developments in adjournment to soluble salts, created by dissolution through chinks from the surface. Existing requirements to a burial place of radioactive waste are described as key aspects of a complex method of an assessment of a mechanical condition of rocks in vicinities of  chambers-  storehouses in seismically active areas which are potentially suitable for storage and burial place  of waste are stated.

Approaches to selection of technological mining schemes based on selective potash seam extraction are described. Progressive technological mining schemes for potash mining company «Belaruskaliy» and the geological conditions of the IV potash horizon are reviewed. Basic aspects of the geomechanical substantiation of parameters of technological mining schemes for conditions of the new potash horizon in the presence of influence of the overlying horizons are also presented. Guidelines for substantiation of progressive mining methods for the conditions of the IV potash horizon (Third Mine, «Belaruskaliy») are developed on the basis of the modeling of the stress-and-strain state of the rocks.

Utilization of exhausted potash mines in Russia as repositories for radioactive waste disposal

Article preview

The growth in energy consumption demands increase in power output of the existing nuclear power plants and construction of the new ones. Radioactive waste requires high-reliable repositories to be disposed. One of the perspective types of the repositories is underground excavations in halogenous formations (created by underground mining or dissolution through boreholes from surface). The new method of radioactive waste disposal is offered in the paper.

Problem of complex mining of potassium-salt and oil deposits on the example of Solikamsk depression

Article preview

Complex geologic conditions of reservoir deposits and insufficient data on the properties and structure of rock formations often lead to mine accidents. Joint mining of salt and oil formations within one mining allotment at different depths can increase the risk of mine flooding. The article presents the main methodological approaches to justify the feasibility of mining of oil deposits in the zone of salt strata spreading. The article also provides a list of the main problems, the solution of which is necessary to ensure safe joint development of oil and salt deposits.

The main stages of their development are considered: before the Great Patriotic War (1941-1945), during the war and in the post-war period. A brief characterization of these stages is given. Brief biographies of key figures who contributed to the successful formation of mining education at the St. Petersburg Mining Institute are given. The traditions of teaching mining engineering disciplines are revealed. Teaching traditions are based on both analytical and experimental and experimental-analytical teachers, whose knowledge is based primarily on their own industrial and scientific experience.
