Engineering and geomechanical forecast for waste disposal in underground caverns including earthquake-prone zones

The article aims at obtaining representative scientifically based data to determine parameters of a necessary-safe condition of the rock massif (RM) in underground waste diposal caverns zones, including earthquake-prone zones. The main requirements for underground caverns for hazardous waste disposal and for their construction technology are described. The subject of the research is underground solution caverns in halogen rocks. Data for justification of safe waste disposal conditions in underground salt caverns and its stages are presented. A complex approach to the solution of the research problem is described. The main aspects of dynamic influence of seismic waves on underground caverns stability are considered. Taking into account seismic-risk zoning data on the research region some significant parameters of a possible seismic impact on the experimental cavern are calculated. The article points out the necessity of superincumbent rock and surface displacement assessment for the experimental site zone using the suggested complex approach and including the analysis of surveying data and results of rock mass geomechanical modeling.

Complex method of assesing mechanical condition of rocks in vicinity storehouses of radioactive waste

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.

Designing of complex mining operations in coal mines

The basic laws of gas filtration at different stages of coal deposit mining are considered. The technique used for studying complex development of power resources of coal deposits, allowing with reference to concrete conditions to receive engineering dependences for a quantitative estimation of all key parametres of investigated processes is given. On the basis of the developed approach to complex development the algorithm of the practical solution of the problem is offered.

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

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.
