Embodiment Construction

[0019] like figure 1 Shown, the present invention comprises the following steps:

[0020] a. Collect geological data and gravity data of known uranium deposits in the basin, and determine the ore-controlling structure characteristics of sandstone-type uranium deposits.

[0021] b. Carry out airborne gamma ray spectroscopy in the basin to obtain the raw count rate of the uranium window.

[0022] c. Correct and convert the original count rate of the uranium window, obtain the data of the aerial release uranium content, count the aerial release uranium content data in the basin, make the aerial release uranium content contour map, and screen out the aerial release uranium abnormality and the aerial release uranium high field.

[0023] d. Conduct ground verification of the screened airborne uranium anomalies and aerial uranium high fields, carry out ground gamma energy spectroscopy, and determine the location of ground radioactive anomalies and ground radioactive high fields, cen...

Abstract

The invention relates to a method for quickly searching a basin concealed sandstone-type uranium mine. The method comprises the steps of collecting the geological and gravity data of the basin uraniummine, and researching the ore control structure features of the sandstone type uranium mine; carrying out aviation gamma energy spectrum measurement to obtain an original counting rate of the uraniumwindow; correcting and converting the counting rate of the original uranium window, solving the uranium content, and screening aerial uranium abnormities and high fields; carrying out ground verification on the abnormal or high field, collecting a soil chemical probe sample, analyzing the contents of uranium and radium elements, and solving a uranium and radium balance coefficient; performing constraint by using the uranium radium balance coefficient, calculating the radium content of the measurement area by using aerial uranium content data, and screening radium anomalies and high fields; and making a radium anomaly and high-field distribution diagram, and delineating a sandstone type uranium mine prospecting favorable area in combination with the ore control structure. According to themethod, radium abnormal information of the deep-source uranium decay daughter can be effectively extracted, the basin concealed sandstone type uranium mine favorable area can be quickly delineated, and the method is provided for searching for the concealed uranium mine in the basin.

Description

technical field [0001] The invention relates to a method for uranium ore exploration, in particular to a method for rapidly searching for concealed sandstone-type uranium deposits in basins. Background technique [0002] Sandstone-type uranium deposits in basins occupy the main position in uranium exploration in my country. However, after years of exploration and development, shallow outcropping deposits have been basically identified. It is becoming more and more difficult to find uranium deposits, which directly affects my country's nuclear energy security. It is of great significance to ensure the national security of our country to further explore hidden or deep sandstone-type uranium ore prospecting methods, realize breakthroughs in the prospecting of sandstone-type uranium deposits in my country's basins, and achieve self-sufficiency in uranium resources. Contents of the invention [0003] The purpose of the present invention is to provide a method for quickly search...
