The study is the first experience to assess the possibility of obtaining clean garnet material from garnet-mica schist from waste Keivy area of Kola Peninsula using electric pulse disintegration. It is shown that the fraction +0.25-0.5 almandine garnet crystal crushed using electric pulse disintegration material and after it washing upward flow of fluid contains up to 94% clean garnet.

To improve the technology of opening and development of oil fields for increasing the completeness of subsoil use, the prospects of using the electric pulse method of drilling are discussed. Validated the concept of creating an electric pulse tunnel system based on submersible source of high-voltage pulses with controllable formation of work space for increasing its maneuverability and creating special technological outputs in a rock mass for forming a cluster of slant and horizontal boreholes with most complete c...
