射气测量在寻找隐伏构造中的应用

The Application of Emanation Measurement In Finding Hidden Structure

射气测量是使用射气仪测量土壤、水及大气中射气的浓度,并通过研究射气浓度的分布特征来解决某些地质问题的一种放射性测量方法,也是寻找构造的有效方法之一。该方法适用于地形较复杂,松散覆盖层分布广泛的地区,具有测量深度大、方法简便、技术成熟、经济等特点。文章简要地介绍了地面射气测量的勘探原理、野外工作方法及资料解释方法,并通过工程实例,对比已知构造和隐伏构造上射气浓度曲线与构造位置、倾向和倾角的关系,分析其在寻找隐伏构造的可行性。

Emanation measurement is one kind of radioactive prospecting method of surveying the concentration of emanation in soil, water, atmosphere by emanometer, by studying the distribution characteristics of emanation concentration to solve certain geological problems. This method is also one of efficient method to search structure. It is suitable for the area with complicated terrain and large loosening layer and with the characteristics as wide surveying depth, easy to use, mature technology and economy. This paper briefly introduces the principle of ground emanation prospecting, method of field word and data interpretation; through the engineering case, comparing with the relationship between emanation concentration curve of known and hidden structure and the location, tilting direction, inclination to analyze its practicality in searching hidden strueture.
