Initiation of electrical discharge by exothermal compositions at destruction of firm soils

Control of a high-voltage discharge-pulse installation when implementing technological modes of an electrochemical explosion

“…Work [7] reports a diagram of the relationships of the main physical processes in the discharge-pulse treatment and their effect on the output indicators in the processing of minerals; however, there is no analysis of multi-pulse energy input. The use of single-pulse energy input is also considered in paper [8]. The authors estimated the volume of destruction and pressures generated by the use of HECE in the destruction of strong soils with single-pulse energy input.…”

“…compared HECE with an electric explosion without the use of exothermal mixtures in terms of the volume of destroyed soils but did not perform analysis of the WEM combustion completeness and did not assess energy efficiency. Our analysis of works [6][7][8] reveals that the implementation of HECE at a single-pulse energy input and, therefore, when using a single-circuit scheme of PCG, is not effective due to incomplete combustion of the applied exothermal compositions because of a short-term nature of the pressure pulse generated by a high voltage discharge.…”
