Deep uranium mineralization information detection method

Abstract

The invention belongs to the technical field of uranium resource prospecting methods, and particularly relates to a method capable of effectively detecting deep uranium mineralization information. The method comprises the following steps of (1) setting measuring points in a working area, placing an activated carbon detector on the ground at each measuring point, simultaneously digging a round pit in the ground at each measuring point, and burying an activated carbon detector in each round pit; (2) taking out the ground and underground activated carbon detectors at each measuring point, and measuring radon concentration values on the ground and at an underground depth h; (3) calculating a perpendicular change gradient value G of radon concentration at each measuring point; (4) calculating a radon concentration value at a burial depth of 40cm at each measuring point; (5) calculating a mineralization information index Ei corresponding to an ith measuring point; (6) identifying advantageous areas for deep uranium mineralization by adopting a concentration and frequency fractal method; (7) determining areas with mineralization information indexes E greater than pm as the advantageous areas for uranium mineralization according to identifiers, determined by the step (6), of the advantageous areas for uranium mineralization.

Description

technical field [0001] The invention belongs to the technical field of uranium resource prospecting methods, and in particular relates to a method capable of effectively detecting deep uranium mineralization information. Background technique [0002] The method of measuring radon by activated carbon adsorption measures the decay progeny of radon 214 Pb and 214 The intensity of gamma rays emitted by Bi can be used to determine the concentration of radon in soil, and further provide a basis for uranium ore prospecting. This method has the advantages of anti-interference, good stability, high precision and good repeatability, and is one of the commonly used uranium detection methods. However, the concentration of radon in soil is often affected by factors such as the thickness of the overburden layer and the humidity of the environment, and cannot accurately reflect the information of deep uranium mineralization.

Problems solved by technology

However, the soil radon concentration is often affected by factors such as the thickness of the overburden layer and the environmental humidity, and cannot accurately reflect the information of deep uranium mineralization.

[0003] The commonly used working procedure of activated carbon adsorption radon measurement method is to dig a deep pit underground, place the activated carbon detector in it to measure the soil radon concentration, and the measured result is only the soil radon concentration value at a certain depth, and does not reflect the soil radon concentration. It is impossible to effectively determine whether the detected radon anomaly is caused by deep uranium mineralization
