含量-面积法和奇异性分析法在采用测氡法探测采空区中的应用

Application of Content-area Method and Singularity Analysis in Exploring Gob by Radon Value Method

在氡值数据处理过程中,由于传统统计方法应用于低放射区域具有一定的局限性,运用含量-面积法对山西省某公司场地探测区地面测氡结果进行数据分析,并首次应用奇异性分析法对其进行结果补充,所得采空区范围与对该区进行的其他物探方法综合解译成果基本相符。结果表明,两种方法的结合使用,能有效综合含量-面积法的简单可行性与奇异性分析法的局部灵敏性,在处理采空区氡值数据时具有明显优势。

Typical statistic method has some limitation for low radiation area in processing data of radon value. This paper applied content-area method to processing radon value from a surface test of a company,Shanxi Province,and firstly applied singularity analysis to supplying result. Gob range determined by this method was accordance with comprehensive explanation fruit from another geophysical method. Results showed that combination application of two methods would effectively utilize simplicity of content-area method and local sensitivity of singularity method in processing radon value data for detecting gob.
