Problems solved by technology

[0002] The radon method is an important exploration method in the field of uranium ore exploration. This method indicates that sandstone-type uranium deposits often have the characteristics of "double peak" profile anomalies and low anomalies sandwiched by ring-like anomalies. There are great difficulties in the location and interpretation of deep uranium deposits, and it is difficult to accurately identify and delineate deep uranium deposits

Abstract

The invention relates to a three-dimensional radon abnormality identification method and system for deep sandstone type uranium mineralization information. This method uses the measured radon concentration value of the spatial point to process the three-dimensional grid to calculate the difference radon concentration of each point of the new scattered point data, and calculates the unknown deeper difference radon concentration through the nonlinear fitting of the vertical and vertical difference radon Values, through the grid processing of new scattered point differential radon concentration values ​​and unknown deeper differential radon concentration values, and according to the abnormal trend analysis of the three-dimensional contour map after grid processing, the positioning of deep uranium mineral resources is realized. The invention can improve the accuracy of deep uranium ore prospecting.

Description

A three-dimensional radon anomaly identification method and system for deep sandstone-type uranium mineralization information technical field The present invention relates to the technical field of uranium prospecting geophysics, particularly relate to a kind of deep sandstone type uranium mineralization information Three-dimensional radon anomaly identification method and system. Background technique Radon method is an important prospecting method in the field of uranium prospecting, and the method indicates that the sandstone-type uranium ore often presents a "double peak" profile. features such as low-level anomalies sandwiched by surface anomalies and ring-like anomalies, which have important implications for the localization and interpretation of deep uranium deposits It is difficult to accurately identify and delineate deep uranium deposits. Sandstone-type uranium ore overburden stratum is gentle, the same stratum The background value of radon concentration ch...
