Embodiment 1

[0085]Seefigure 1The present invention provides a method for a three-dimensional uranium mine advantageous location, including the following steps:

[0086]S1: Get the soil radon concentration value;

[0087]Specifically, in the range of uranium exploration zones, the measuring instantaneous soil radon measurement is carried out from 20 m × 20 m sizes to 50 m × 50m, and the depth of air is 0.7 meters -1.2 meters. Get the soil radon concentration value at each measurement point.

[0088]It should be noted that in the present embodiment, the network degree of the mesh is 20 meters × 20 meters, and the air intake depth is 1 meter. The soil radon concentration value can be accurately obtained by the network degree and the depth of the air of the net.

[0089]S2: Treatment of the soil radon concentration, acquisition of soil radon concentration value anomalies and soil radon concentration lines;

[0090]S21: Getting the soil radon concentration value is specific:

[0091]S211: Calculate the soil radon con...

Abstract

The invention relates to a method for delineating a favorable three-dimensional uranium mineralization part. The method comprises the following steps: acquiring a soil radon gas concentration value; treating the soil radon gas concentration value, and obtaining the abnormal range of the soil radon gas concentration value and the abnormal range of the soil radon gas concentration contrast value; according to the abnormal range of the soil radon gas concentration value and the abnormal range of the soil radon gas concentration contrast value, obtaining the favorable earth surface plane uranium mineralization range; carrying out three-dimensional wide-area electromagnetic measurement work in the favorable earth surface plane uranium mineralization range to obtain three-dimensional wide-area electromagnetic measurement data; calculating apparent resistivity according to the three-dimensional wide-area electromagnetic measurement data; performing three-dimensional inversion on the apparent resistivity data to obtain a three-dimensional resistivity data distribution body; acquiring three-dimensional resistivity distribution characteristics according to the three-dimensional resistivity data distribution body; and according to the three-dimensional resistivity distribution characteristics and uranium mineralization geological characteristics, delineating a three-dimensional uranium mineralization favorable part. Through the method, the favorable three-dimensional uranium mineralization part of the sedimentary diagenetic sandstone type uranium deposit can be rapidly and accurately delineated.

Description

Technical field[0001]The present invention relates to the field of uranium exploration techniques, in particular to a circle of a three-dimensional urban minerality.Background technique[0002]In the deposition of the rock type sandstone uranium ore detection, the use of radioactive measurement methods can be coarsely circulated on the surface of uranium into the mineral minerality, but it is difficult to relatively accurately set the advantageous part of the three-dimensional uranium into the mine, so that the uranium depression of the region See the low ie rate, leading to high exploration costs, so that the economic difference of deposition of rock type sandstone uranium deposits, which seriously restricts the strength of deposited rock sandstone uranium deposits.[0003]Therefore, in order to accurately, the economy is deposited into a three-dimensional mine-like mine-like mine, locking the three-dimensional spatial position of uranium minerals, providing more accurate spatial coord...
