电磁频率测深法在山西阳曲找煤中的应用

Application of electromagnetic frequency Sounding method to Yangqu area in Shanxi province

在山西阳曲地区运用电磁频率测深法进行地面探测 ,对所采集的数据采用曲线类型分析和曲线特征点分析进行定性解释 ,用广义逆矩阵反演法通过人机对话的形式进行定量反演计算 ,并对全区资料进行相位转换处理 ,推断解释出本区有含煤构造存在 ,钻探资料的验证表明结论正确。用电磁频率测深技术寻找出储量为 10多亿吨的大煤田 。

The method of frequency electromagnetic(FEM) was used to detect coal in the area of Yangqu Shanxi province. The data observed outside was processed by the method of analyzing curve type, and recognized by the method of analyzing feature point. The method of generalized inverse matrix was used to calculate the overall data by the way of person computer dialogue. Getting the conclusion is that there are coal structure reserved in this area. The result of bore shows that the interpretation conclusion was right. A coal field that reserves one billion tons had been discovered after working in the area of Yangqu ShanXi with the method of electromagnetic frequency sounding. The mistake that there are no coal underground in this area has been corrected.
