无线电波透视法中“异常下限”的引入及其应用分析

Introduction and application analysis of abnormal lower limit in radio wave penetration method

无线电波透视法作为煤矿井下工作面内构造等地质异常探测的重要手段,其在异常边界的选取中具有很大随机性和不确定性。作者用数理统计的方法尝试确定较唯一的异常边界值,并通过引入一个“异常下限”的概念来进行异常的识别。在山西兴县关家崖煤矿采用该方法进行异常的识别,较可靠地圈定出地质异常区,通过各矿区的探、采对比,得出合理的异常值。

Radio wave penetration method,as an important means of detecting geological anomalies such as structures in underground working faces of coal mines,has great randomness and uncertainty in the selection of anomaly boundaries.The authors attempt to determine a more unique boundary value for anomalies by means of mathematical statistics and identify anomalies by introducing the concept of“anomaly lower limit”.This method is used to identify anomalies in Guanjiaya coal mine in Xingxian of Shanxi Province,and reliably delineates geological anomaly areas.Through the comparison of exploration and mining in various mining areas,reasonable anomaly values are obtained.
