SUBRESONANT LOAD ENERGY REGULATION WHEN ELECTROTHER0MAL ROCK FRACTURING

Oleg Terentiev, Anton Kleshchov

Abstract


It is determined that inductive plasma flows energy regulation will reduce specific energy intensity of crystalline structures fracture with the help of n-component fracture system accommodation. Rock fracturing is considered at the level of crystalline structures (femtolevel). Crystalline structure oscillations are caused by the presence of internal and external factors. External factors are represented by changing the parameters of inductive plasma flows: concentration; temperature; energy; exposure time of crystalline structure. Opportunities stand it possible to determine the inductive plasma physical parameters impact on crystalline structure of the samples, which were prepared for experimental tests. For the first time the mathematical model of plasma flow energy is introduced, which differs from the existing ones with the fact that it links discharge circuit inductance and current of the electrothermal rock fracturing plant with the characteristics of its operatingtool – plasma flow. This allows to reduce specific energy intensity of crystalline structure fracturing by varying discharge circuit inductance and current when changing the structures parameters with the help of switches system.
