DEVICE FOR DETECTION OF CONDUCTING PARTICLES IN ROCK Russian patent published in 2002 - IPC

FIELD: mining industry; device intended for detection of conducting particles in rock. SUBSTANCE: proposed device has sensitive element made in form of group of pairs of electrodes separated by dielectric gaps of different width. Each pair os electrodes which differs from other ones in width is provided with analyzer. Adjacent edges of adjacent electrodes are wavy in shape; crests of waves of edge of one of electrodes are located in troughs of wavy edge of adjacent electrode forming wavy dielectric gap between above-mentioned edges. EFFECT: enhanced specific efficiency due to considerable increase of length of contact edges of electric pair of electrodes separated by wavy dielectric gap at retained limited overall length of electrodes. 4 cl, 4 dwg
