曲面磨光法及其在煤田隐伏构造预测中的应用

趋势面分析是煤田中预测隐伏构造的常规方法。在认真研究前人工作和地质特点的基础上,本文提出了用曲面磨光法进行构造预测。此法的最大特点就是平板磨光后仍为平板,且与原平板重合,这一优良的数学特性,使得它在构造预测方面优于趋势面等方法。通过对模型和实例的分析,证明曲面磨光法在构造预测,特别是对隐伏断裂构造的预测是相当有效的。

Method of Curved Surface Smoothing and Its Application to Forecasting the Buried Structures in Coalfield

The trend surface method is a conventional technique for forecasting the baried structures in coalfield. According to predecessors exprerience and geological characteristics this paper puts forward a new method for forecasting gological structures, namely the method of curved surface smoothing. The characteristic of the new method is that the smoothed flat remains a flat and the flat coincides with the original one. Because of the excellent mathematical characteristic, the curved surface smoothing method is more superior than trend surface and other methods in structural forecast. Through the analysis of models and examples, results show that the curved surface smoothing method is feasible for the structural forecast, especially for buried fractured structure forecast.
