摘　　要：为了充分挖掘各类物探成果包含的信息,改变以往物探成果解释对技术人员经验过于依赖的不足,提高综合物探成果解释的效率和准确率,真正实现物探成果的综合解释,利用聚类分析算法,对瞬变电磁法和无线电波坑道透视法探测成果预处理后的数据进行聚类分析,将综合物探探测数据分为若干个类别,结合地质资料判断各组数据异常程度,实现物探成果综合解释。在山东某矿开展了瞬变电磁法与无线电波坑道透视法综合探测,利用聚类分析算法对物探成果重新进行了综合解释,保留原有异常区1处,新解释异常区1处,经矿方实际回采验证,证明聚类分析考虑影响因素更加全面,异常区划分更加合理、准确、无遗漏,能够避免传统解释方法对分析解释人员经验依赖较高,可能存在人为遗漏异常区的风险。In order to fully excavate the information contained in geophysical results and avoid the lack of relying too much on the experience of technicians in the previous geophysical exploration results to improve the interpretation efficiency and accuracy of integrated geophysical results and truly realize the integrated geophysical interpretation.The interpretation cluster analysis was used to interpret the integrated geophysical results to classify the detection results.The integrated geophysical exploration of TEM(transient electromagnetic method)and radio wave tunnel method was carried out in a mine in Shandong province and the cluster analysis was used to interpret the integrated geophysical results again.One original abnormal area was reserved and one abnormal area was newly divided.The cluster analysis abnormal area is verified by the mine.
