| 摘 要： | 针对煤田火烧区烧变岩体的单一磁化模型反演解释难以达到预期效果的缺点,根据烧变岩体热剩磁随温度及深度的变化规律,结合小波多尺度分解二阶逼近,消除区域场,建立了非均匀磁化烧变岩体二度半多边形体反演模型。实例计算,效果良好。

| Abstract: | The principles of 2.5 dimension polygon interactive inversion in magnetic exploratory data in the area of the burnt coal are elaborated.The regularities of the thermo-remnent magnetism intensity of combustion-metamorphic rocks changed by coal's burning are analyzed,and the model of mutative magnetization related to the depth is established.Therefore,with the result of the second order approach part of wavelet multi-scale analysis,aborative operation by 2.5 dimension polygon for plane prism interactive inversion is carried on actual magnetic exploratory data of a coalfield.It is indicated that magnetic anomaly dealt with this method reflects the obliquity,buried depth and idiographic shape of the burnt coal more exactly. |
