METHOD FOR COORDINATES DETERMINING ACOUSTIC EMISSION SOURCES IN ROCK MASSIVE Russian patent published in 1994 - IPC

Abstract RU 2009528 C1

FIELD: mining industry. SUBSTANCE: bore holes acoustic emission pickup-receivers placing on are making in uniform rock massif which dimensions, acoustic waves damping factor, velocity of longitudinal and transverse acoustic waves are known. Pickups are placed at tetrahedron vertexes and on its geometrical center. The distances between pickups are determining from formula cited in invention prescription. EFFECT: better method for rock pressure dynamics testing. 4 dwg
