METHOD FOR EVALUATION OF IRREGULARITY IN DISTRIBUTION OF ABSORBING CAPACITY OF ROCK MASS

摘要

FIELD: mining industry. SUBSTANCE: method for evaluation of irregularity in distribution of absorbing capacity of rock mass consists in drilling holes in rock mass and installation of isolating plugs. Electrical pickups are installed by intervals in rock mass depth in different directions and at equal distance from hole axis. Fluid in injected over all hole length, and irregularity in distribution of absorbing capacity of rock mass is evaluated proportionally to irregularity in distribution of values of measured potentials of filtration electrical field. EFFECT: higher efficiency. 3 dwg
