近几年来,应用壤中汞气测量在512、513等铀矿区取得了较好的地质效果。但在投入大面积生产时就显出了野外采样工具笨重和方法的有效灵敏度低等弱点。钋法找铀矿已在生产中较为广泛的应用。能否用钋法副样进行土壤汞量测量(简称土壤汞法)?土壤汞法能否反映深部铀矿信息?这是生产中提出的问题,需要通过试验解决。为此,我们从1982年至1983年先后在513和510两个矿区进行了此项试验与应用的研究工作,并已取得较好的成果。本文就其主要成果进行讨论。
In recent years, the application of mercury gas measurement in the soil 512, 513 and other uranium mining area has achieved good geological results. But when it comes to mass production, it shows the weakness of the field sampling tool bulky and the low effective sensitivity of the method.钋 law to find uranium ore has been more widely used in production. Is it possible to use the sample method to measure soil mercury content (referred to as soil mercury method)? Can the soil mercury method reflect the information of deep uranium deposits? This is a problem raised in the production and needs to be solved through experiments. Therefore, from 1982 to 1983, we carried out the research work on this experiment and application in two mining areas 513 and 510, and achieved good results. This article discusses its main achievements.
