Problems solved by technology

[0003] The radionuclides contained in the deep concealed uranium deposits are constantly decaying to produce new nuclides in the process of transmission to the surface. The radioactive information has experienced layers of barriers from surrounding rocks and cap rocks during the transmission process, and when it reaches the surface, the abnormal information is very Weak, part of the information is covered by surface information, and a single information anomaly is prone to multiple solutions, which brings great difficulties to the interpretation of deep uranium mineralization anomalies

Embodiment Construction

[0057] A method for delineating anomalous far-field areas with radioactive comprehensive information according to the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0058] A method for delineating the anomalous far-sighted area of ​​radioactivity comprehensive information of the present invention uses Boolean logic to extract the abnormal surface of each data layer of the measured data of the gamma energy spectrum, the measured data of radon and its progeny, and other data obtained based on the above data, and uses the abnormal The ratio of the overlapping area of ​​the surface and the known ore body on the surface projection surface to the known ore body on the surface projection surface is the score, and the various data layers are integrated, and the integrated comprehensive information anomaly is used to delineate the abnormal prospect area. Prediction of deep uranium resources.

[0059] Specifically, th...

Abstract

The invention belongs to the field of radioactive geophysical exploration in uranium exploration and specifically relates to a radioactive integrated information anomaly prospective area delimitationmethod. The method is characterized by, based on Boolean logic, extracting gamma spectrum actually-measured data, radon and daughter actually-measured data thereof and abnormal surface of each data graph layer of other data obtained based on the data above; and with the ratio of the overlapped area between the abnormal surface and a surface projection surface of a known ore body and the surface projection surface of the known ore body being score, carrying out comprehensive integration on the data graph layers, and delineating an abnormal prospective area by utilizing the integrated information anomaly to predicate deep uranium resources. The radioactive integrated information abnormal prospective area delimitation method can accurately delimitate deep uranium mineralization anomaly and provides reference basis for deep uranium prospecting and engineering exploration.

Description

technical field [0001] The invention belongs to the field of radioactive geophysical prospecting in uranium ore prospecting, and in particular relates to a method for delineating abnormal far-sighted areas with radioactive comprehensive information. Background technique [0002] According to the current drilling revelations, deep uranium deposits have great potential for prospecting, and it is of great significance to carry out research and innovation in deep uranium deposit exploration technology. [0003] The radionuclides contained in the deep concealed uranium deposits are constantly decaying to produce new nuclides in the process of transmission to the surface. The radioactive information has experienced layers of barriers from surrounding rocks and cap rocks during the transmission process, and when it reaches the surface, the abnormal information is very Weak, part of the information is covered by surface information, and a single information anomaly is prone to multi...
