我们都知道在铀矿床的表生作用带中其放射性平衡大都遭到不同程度的破坏,并由于气候、岩性、水文地质条件及地质构造等因素的不同,使某些矿床的氧化带极为发育,平衡有时变得很复染,尤其是外生矿床更是如此。当我们在储量勘探中采用物探方法(测井和辐射取样)确定矿石的含量时,放射性平衡系数确定的正确与否,直接影响到储量计算的准确性。同时,在某些条件下,根据平衡变化的规律还有可能提供有关铀矿被破坏和富集过程的资料。因此,对铀矿床放射性平衡变化规律的研究是勘探过程中物探工作者的重要任分之一。但是由于某
We all know that most of the radioactive equilibrium in the epiphytic belt of uranium deposits has been destroyed to different extents. Due to different factors such as climate, lithology, hydrogeological conditions and geological structure, the oxidation zone of some deposits is extremely developed The balance can sometimes become very complicated, especially in exogenous deposits. When we determine the ore content by geophysical methods (logging and radiation sampling) in reserve exploration, the correctness of the determination of the radioactivity balance coefficient has a direct impact on the accuracy of the reserve calculation. At the same time, under certain conditions, it is also possible to provide information on the process of destruction and enrichment of uranium deposits, based on the law of equilibrium changes. Therefore, the research on the regularity of the variation of radioactive balance of uranium deposit is one of the most important tasks of geophysical exploration workers in exploration. But due to some
