Deep uranium mine two-dimensional radon gas difference detection method

Abstract

The invention belongs to the technical field of uranium ore exploration geophysics, and particularly relates to a deep uranium ore two-dimensional radon gas difference detection method, wherein the method comprises the following steps: step (1) selecting a region and positioning a measurement point; step (2) drilling and embedding activated carbon adsorbers according to the positioning measuring point determined in the step (1); step (3) measuring the radon concentration of the activated carbon adsorber in each hole in the step (2); step (4) calculating the soil radon gas concentration difference of the measuring point of a measuring line; step (5) calculating the soil radon concentration difference sum of the measuring points of the measuring line; step (6) constructing two-dimensional space scatter data according to the soil radon concentration difference of the measuring points of the measuring line in the step (5); and step (7) predicting the positioning of the deep uranium ore. The activated carbon adsorption devices are buried in shallow soil by adopting a longitudinal section two-dimensional measurement method of radon and daughters thereof, the concentration of radon gas indifferent depth layers of the longitudinal section is detected, the longitudinal section two-dimensional radon difference is calculated and obtained, and deep uranium mineral resource target area delineation is realized.

Description

technical field [0001] The invention belongs to the technical field of uranium ore prospecting geophysics, and in particular relates to a two-dimensional radon differential detection method in deep uranium ore. Background technique [0002] Uranium mineral resources are the strategic granary of the nuclear military industry. Especially with the rapid development of nuclear power, the demand for uranium ore is increasing day by day. At present, shallow uranium deposits on the surface have been basically discovered. The exploration of deep uranium deposits is the key to solve the current tight supply and demand of uranium deposits. The only way, however, there are still deficiencies in the deep uranium exploration technology. The soil radon gas measurement method is an important exploration method in the field of uranium ore exploration, including two measurement methods: instantaneous measurement and cumulative measurement. The soil obtained by these two measurement methods T...
