[Abstract]:In order to construct the information extraction technology of deep sandstone type uranium mineralization, this paper discusses the theoretical basis of extracting deep uranium mineralization information based on radioactive geophysical method. The radon anomaly two-dimensional raster contrast and fractal filtering are used in this paper. The radon concentration data measured in Erlian basin and Junggar basin of China were processed by radon and radon ratio calculation methods. At the same time, the method of evidence weight was used to integrate geology, soil radon and vehicle gamma spectrum. The applied research on quantitative extraction of multivariate information has been carried out in the layer of ore-forming favorable information such as aviation gamma spectrum. Through data processing, the surface information has been effectively suppressed, and the drift or false anomaly of radon anomaly has been eliminated. The abnormal information after processing is positively related to the vertical projection of orebodies on the surface and ore-controlling structures, which provides technical support for the prospecting of deep sandstone-type uranium deposits in northern China.
