Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0032] A method for identifying deep uranium mineralization information provided by the present invention, the method specifically includes the following steps:

[0033] Step (1) Use a handheld GPS locator to determine the measurement location within the survey area.

[0034] Step (2) Take a soil sample at a depth of 40 cm to 60 cm at the position determined in step (1) with tools such as shovels and hoes.

[0035] Step (3) using a gamma spectrometer to measure the energy spectrum uranium content in the pit after the soil sample is taken in step (2).

[0036] Step (4) The soil sample obtained in step (2) is dried in the shade, crushed, and passed through a 120-mesh sieve, and a -120-mesh soil sample is taken.

[0037] Step (5) Dry the -120 mesh soil sample in step (4) in an oven at 110° C. for 2 hours.

[0038] Step (6) uses a medicament to...

Abstract

The invention belongs to the technical field of uranium exploration and discloses a method for identifying deep uranium mineralization information in particular. The method for identifying deep uranium mineralization information comprises the following steps: (1) determining the measuring position in the measuring area; (2) taking the soil sample from the measuring position determined in the above step (1); (3) measuring the gamma spectrum of uranium content in the pit after taking the soil sample in the above step (2); (4) drying, grinding, and sieving the retrieved soil sample; (5) drying the sieved soil samples in the above steps (4); (6) extracting component uranium from the soil sample after drying by step (5) by using a medicament; (7) determining the component uranium extracted in the above steps (6); (8) making a plane contour map; (9) delineating abnormal areas; (10) according to energy spectrum uranium, component uranium, component uranium / energy spectrum abnormal uranium ratio, identifying deep uranium mineralization information. The method for identifying deep uranium mineralization information can greatly improve work efficiency and shorten the prospecting period.

Description

technical field [0001] The invention belongs to the technical field of uranium ore exploration, and in particular relates to a method for identifying deep uranium mineralization information through ground gamma energy spectrum measurement and soil component uranium measurement. Background technique [0002] At present, my country's nuclear industry has entered a stage of rapid development, especially with the development of nuclear power, the demand for uranium resources has grown rapidly, and uranium resources have become an important pillar for the sustainable development of my country's nuclear power. After more than 60 years of uranium exploration in my country, most of the superficial ore and outcrop mines have been discovered. In recent years, the main task of geological prospecting has shifted to searching for deep concealed uranium deposits. With the increase of the depth of prospecting, the original conventional exploration technology can no longer meet the needs of...
