FIELD: mining.SUBSTANCE: method includes drilling of a well, generation of a slot with rock rupture by a plastic substance in the specified plane. Initially the slot is formed with the plastic substance, electric resistance of which depends on pressure, and then the plastic substance with dielectric properties is injected into the slot from the place equidistant from its borders, thus creating from the initially injected plastic substance a ring, which is used to receive electromagnet and elastic waves from formation of cracks in rocks. Assessment of stressed condition of rocks is carried out by parameters of received waves.EFFECT: higher efficiency of the method due to reduction of labour intensiveness of its realisation, reduced effect of massif structure at a measurement result and expanded area of information collection about rock condition.4 cl, 3 dwg |
