Embodiment Construction

[0055] The technical solutions and beneficial effects of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0056] See attached figure 1 The method for selecting a scientific deep drilling site for volcanic rock type uranium ore field of the present invention comprises the following steps:

[0057] S01: Identify the regional uranium mineralization background

[0058] Select areas with good uranium mineralization background by identifying the regional uranium mineralization background as a selection area; the identified area is usually a relatively large range, for example, it can be nationwide or provincial;

[0059] S02: Identify whether the overall structure of each volcanic basin in the primary selection area is favorable for mineralization

[0060] Identify at least one volcanic basin whose overall structure is favorable for mineralization in the primary selection area as a secondary selection a...

Abstract

The invention discloses a scientific deep drilling site selection method of a volcanic type uranium ore field. The method includes following steps: S01: recognizing an area uranium mineralization background, and screening an area with good uranium mineralization background as a primary selection area via the recognition of the area uranium mineralization background; S02: recognizing whether the overall structure of each volcanic basin in the primary selection area is good for mineralization, and recognizing at least one volcanic basin whose overall structure is good for mineralization in the primary selection area as a secondary selection area; S03: selecting abnormal positions in the secondary selection area by employing geophysical and geochemical methods; and S04: determining the deep drilling site according to the abnormal positions. According to the selection method, the range is gradually reduced from large to small, the deep drilling site is determined, the process is clear, the implementation is convenient, and the deep drilling construction of the deep drilling site determined by the method can strongly guarantee smooth operation of uranium ore exploration and research work.

Description

technical field [0001] The invention relates to the field of uranium ore geological research, in particular to a method for selecting a scientific deep drilling site for a volcanic rock type uranium ore field. Background technique [0002] my country's uranium mine geological work began in the 1950s. After more than half a century of uranium mine exploration work, a considerable number of uranium deposits were discovered, making historic contributions to the development of my country's nuclear industry. However, most of the deposits discovered so far are shallower than 500 meters. In recent years, with the intensification of research and exploration efforts, very good industrial uranium mineralization has been found in some important uranium mining areas at a depth of 1,000 meters. It is too large to carry out research work, such as the dynamics of the deep Earth, the relationship between continental hotspots and uranium mineralization, magma-fluid evolution, the migration a...
