DETERMINATION OF RADON EMANATION AND DIFFUSION COEFFICIENTS IN PASTE BACKFILL MADE OF TAILINGS OF PRIARGUNSKY MINING AND CHEMICAL WORKS

The article is prepared based on measurements of radon emission from paste backfill prepared using uranium ore processing tailings at Priargunsky Mining and Chemical Works. It is found radon mainly emanates from the subsurface layer of the paste backfill with a thickness of 45 mm. Consequently, the radon emission flow is independent of the volume of the paste backfill placed in a stope but depends on the surface of the stope. The most expedient approach to using paste backfill made of uranium ore processing tailings is placement in large stopes with the matched length, width and height dimensions. The total surface of contact with the enclosing rocks is minimal in this case, and the radon emission is also minimal as against the volume of placed backfill.

Keywords

Radon, radon flow density, emanation coefficient, diffusion coefficient, paste backfill, uranium ore processing tailings.
