Abstract
EN: Abstract. The performed analysis of scientific sources confirms the
existence of a small number of publications devoted to the experimental
research of the gasdynamics and plasmodynamics of jets used as a heattransfer
medium in the thermal methods of mine rocks destruction. There
are almost no experimental and theoretical publications related to the
multiple-jet plasmotrons research. The expediency of own experimental
researches performing has been substantiated concerning the lateral inflow
of heat-transfer medium high-speed jets on the borehole surface. An
experimental research has been made of the interaction between the heattransfer
medium high-speed jets and the surface of the borehole imitated
by the through duct. The further prospects of this work are the following:
to determine the gas velocity along the lateral surface of the through duct
and the value of the heating capacity coefficient from the heat-transfer
medium to the lateral surface of the through duct, which imitates the rock
surface in the borehole. These parameters are required for creating a
mathematical model of the brittle destruction of rocks.
