To regulate the impact of explosion in the directional destruction of rocks, it is necessary to use industrial explosives (IE) with a sufficiently wide range of energy, technological and physical-mechanical properties. In some cases, it is even necessary to reduce the volumetric energy density and create controlled systems for energy transfer and extraction. When developing the explosives for the mining industry it should be taken into account that the efficiency of the use of explosives is determined not only by the degree of useful use of the potential energy of the charge, but also by the possibility to control the mechanism of destruction of rocks. The creation of methods of controlling the explosion energy is based on a qualitative change in the mechanism of its action by introducing additives to the PVB composition, improving the technology of preparation, modifying the surface of the energy-intensive metal combustibles.

The tendencies existing in the world practice of underground development of steeply falling deposits of potassium salts by chamber system, testify that one of the most perspective directions of creation of technology of future mining enterprises is reduction of irretrievable losses of a mineral in the subsoil at the expense of increase of chamber stocks of a block by change of its sizes, including increase of height of a storey, in a combination with filling of worked-out space.

In 1978-1981 in PGO Sevzapgeologia was proposed a set of radio-geochemical methods of searching for deposits of muscovite pegmatites, based on their uranium specialization and regular connection of radio-geochemical halos with pegmatite fields in the territory of the White Sea pegmatite province.

One of the directions for the improvement of pyrometallurgical processing is the creation of multi-chamber units, in separate chambers of which processes of a different nature are carried out. Such combined units for ore smelting and slag depletion, conversion and depletion, and smelting, conversion and depletion have been developed in recent years in the USSR and abroad. ...

The specificity of the seismogeological conditions of ore districts composed of crystalline rocks complicates the use of traditional seismic exploration methods of building velocity models based on the generalization of data from the determination of effective velocity. ...

As is known, when using seismic exploration methods, the problem of elastic wave generation is of paramount importance. However, many issues in this area are still very poorly studied. In particular, there is no information about the dependence of the amplitude of seismic oscillations on the size (weight) of the charge, although this issue is of theoretical and practical importance. This paper presents some information on this dependence, obtained on the basis of special experimental work, supplemented by the results of processing of conventional RWCV and DSS seismograms.
