Abstract

During the explosions in the mining industry, there is a problem of the appearance of induced
fracturing from the impact of explosion products on the rock mass. In the intact mass there are cracks
that are formed during the movement of tectonic plates and as a result of solidification of magma
(formation of igneous rock), as well as with human intervention. The induced cracks, merging with
the existing cracks in the mass, form blocks that negatively affect the quality of the destroyed rock
mass. To predict the quality of the explosion, as well as the stability of the rock mass, there are many
ways and methods of measuring fracture. It is not always possible to conduct research to solve
problems, for example, when determining the size of a fracture that develops perpendicular to the
well in rocks with high electrical conductivity. To determine the geometric dimensions of a linear
defect, let us determine the relationship between the radius of a round crack located perpendicular to
the wellbore and the resistance of the massif with this fracture to direct and alternating current.
