METHOD OF DIRECTIONAL HYDRAULIC BREAK OF ROCKS

摘要

FIELD: mining industry. SUBSTANCE: proposed method relates to geotechnological processes of mining of mineral resources and can be used in formation of geothermal circulation systems in low-penetrability rocks. In agreement with method holes are drilled to level of hydraulic break. Through one of them fluid is fed under pressure. At least two coherent energy sources are put into other holes at specified distance from initiation center, vibrations of rock are caused by sources when pressure of fluid in hole reaches not less than 90% of critical one. Thanks to such implementation of method range of its application expands due to formation of cracks in isotropic medium with different stressed deformation state of rock mass at different depths. EFFECT: reduced expenses and time for implementation of method.
