Abstract

The invention relates to the technical field of blocking removing of uranium mines, in particular to seepage-enhancing and blocking-removing liquid for uranium mines as well as a using method and application thereof. The seepage-enhancing and blocking-removing liquid for uranium mines is prepared from a comprehensive blocking remover I, a comprehensive blocking remover II and an anti-swelling displacing liquid. During use of the seepage-enhancing and blocking-removing liquid for uranium mines, inorganic scale pollution at a mine barrel and a blast hole segment is eliminated through the comprehensive blocking remover I, and then hydrogen ions are released through the comprehensive blocking remover II to realize deeper penetration of the comprehensive blocking remover II, so that the reaction area is enlarged, barriers in a uranium channel are removed, and the seepage rate of a uranium layer is improved. Finally, damage caused by clay minerals can be prevented and pollution of the immediate vicinity of a wellbore can be eliminated through the anti-swelling displacing liquid. By adopting the seepage-enhancing and blocking-removing liquid, the problem of blocking of the uranium layer is solved effectively, the secondary pollution of stratum can be prevented, the blocking removing effect can be enhanced, and the blocking-removing valid period is prolonged.

Description

technical field [0001] The invention relates to the technical field of plugging removal in uranium mines, and relates to a seepage-increasing plugging removal fluid for uranium mines and a use method and application thereof. Background technique [0002] At present, in the process of mining uranium in uranium mine formations, due to the influence of rock ore characteristics, liquid injection characteristics and other factors, the Ca in the leachate 2+ , Fe 2+ / total Fe and SO4 2- The concentration is too high, and the drilling and injection volume is low. During the liquid injection process, precipitates mainly composed of sulfate, Fe and Al hydroxides are gradually formed, which makes the wellbore, blast hole and the deep part of the formation blocked and polluted. The mine seam has been damaged by secondary sealing. [0003] At present, in view of the above situation, ordinary pickling well fluid is generally used on site to solve the problem. Although ordinary picklin...
