Method for accurately measuring occurrence of hydrothermal uranium mineralization body

Abstract

The invention belongs to the field of uranium exploration and metallogenic law research, and particularly relates to a hydrothermal uranium mineralization body occurrence accurate determination method, which comprises the following steps: 1, researching a working area metallogenic geological background and metallogenic conditions, and determining a prospecting target area; 2, geophysical prospecting logging is carried out to determine the position and mineralization strength of a drilling exposed uranium body; 3, determining the scale and the accurate depth position of the uranium mineralization body through gamma logging; 4, determining the depth, the inclination and the inclination angle of the mineralized body through ultrasonic imaging logging; 5, carrying out rock core geological logging to obtain uranium mineralization characteristics and mineralization rules; and step 6, determining the occurrence of the uranium mineralization body in combination with geological record and mineralization rules. According to the method, the uranium ore body in-situ occurrence can be accurately, efficiently and rapidly determined, the prospecting efficiency is improved, the prospecting cost is reduced, a basis is provided for uranium ore exploration deployment and adjustment, and the method has good application and popularization value.

Description

technical field [0001] The invention belongs to the field of uranium ore exploration and metallogenic law research, and specifically relates to a method for accurately determining the occurrence of hydrothermal uranium mineralization bodies. Background technique [0002] In response to global climate change and energy security issues, nuclear energy, as a clean, safe, efficient, economical, low-carbon and environmentally friendly energy, has an irreplaceable position. inevitable choice. With the development of nuclear power, there is a significant and long-term demand for uranium resources. The hydrothermal uranium deposits in South my country are an important type of industrial uranium resources in China. After decades of development, some uranium base resources in my country are gradually exhausted, and there is an urgent need to replace uranium resources. To break through deep uranium resources. However, the spatial distribution of hydrothermal uranium ore bodies is con...

Problems solved by technology

[0004] At present, the occurrence of uranium ore bodies is mainly determined according to the structural occurrence of the working area or the occurrence of the ore belt. The general exploration experience believes that the uranium ore body is parallel to the fault (zone) or the occurrence of the uranium ore belt in the working area, but the hydrothermal The occurrence of type uranium ore bodies is very complex and changeable, and the occurrence of ore bodies is composed of multiple groups of directions. In many cases, uranium ore bodies and faults (zones) or uranium ore belts are not parallel to each other, and it is impossible to determine uranium ore bodies based on experience. spatial distribution, it is impossible to accurately analyze the extension of the uranium ore body in the direction and dip

[0005] At present, uranium ore exploration determines the occurrence of uranium ore based on ore-forming laws or experience, which is inaccurate for a single ore body. When calculating uranium resource reserves, it is necessary to conduct different drilling projects for each uranium ore body. Circle connection, due to the inaccurate occurrence of uranium ore bodies, there may be circles connected together that are not the same uranium ore body in two drilling projects, or they are originally the same uranium ore body, but they do not match the exploration experience and are artificially divided into two uranium ore bodies
