Some approaches to secure mining of potash deposits

The basic aspects of safe mining of potash deposits is reviewed. Practical examples of the mechanism and possible consequences of violating the integrity of the waterproof rock strata are described. Use of remote non-destructive monitoring system for non-destructive integrity breeds of the waterproof rock strata is proposed.

Rock displacements in the vicinity of the face of the unsupported excavation

The relationship between displacements of the excavation contour and distance to the excavation face is obtained in the paper. The relationship allows to calculate support pressure with the account for delay of the support installation. Some calculation results of axial forces in the support are given. Calculations are made on the basis of finite-element method with three dimensional models.

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.

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.
