Problems solved by technology

In layman's terms, the current geological exploration of uranium mines is mainly "point-and-point arguments", with a strong purpose, that is, to submit uranium resources. Therefore, in actual work, most of the working means funds are used for engineering disclosure and experimental analysis. , the funds for other work methods are relatively small, so we need to be more efficient in uranium mine geological mapping in actual field work, and other work methods must be carried out in a more targeted and limited range

Embodiment 1

[0042] The technical solution of this embodiment is a method for geological mapping of uranium mines that improves the comprehensive exploration efficiency of uranium polymetallic, and the method includes the following steps in sequence:

[0043] Step 1. Preparation phase

[0044] Step 1.1 Select the route that can pass through the most geological bodies, important structural zones, and representative mineralized zones, and carry out field surveys and profile surveys, so as to initially establish the regional structural framework of the work area, the spatial contact relationship of various geological bodies, and the geological body. Combination sequence, and basically determine the basic mapping unit;

[0045] Step 1.2 In the process of field survey and profile measurement in step 1.1, focus on identification of typical veins, structures and key alterations and collection of typical samples, especially for conventional alterations and uranium and polymetallic mineralization ...

Embodiment 2

[0065] In order to illustrate the specific implementation of the alteration prospecting method, the Baijiayingzi area is taken as an example to introduce how to improve the efficiency and take into account the polymetallic prospecting work in the process of geological mapping of uranium deposits. Due to different actual conditions in different regions, the implementation and selection of some steps may be different.

[0066] Take the 1:50,000 uranium mine geological survey in Baijiayingzi area as an example.

[0067] The area of ​​Baijiayingzi area is 321.94km 2 . In the process of field survey and profile measurement in the early stage of mapping, the identification and feature identification of typical lithology, veins, structures and alterations were emphasized. Then, based on this understanding, we carried out route geological survey. The biggest feature of this work in uranium mine geological survey is radioactivity measurement. The identification and trace inspection ...

Abstract

The invention belongs to the field of uranium ore geological exploration and relates to a uranium ore geological mapping working method that improves the efficiency of uranium polymetal comprehensive exploration. Carry out field reconnaissance and profile measurement work, focusing on the identification and sample collection of typical veins, structures and key alteration features; lay out specific routes for carrying out geological survey work, including systematic observation routes and inspection routes; carry out systematic geological survey of observation routes, Obtain potentially meaningful alteration point sections and take samples for testing; comprehensively complete radioactivity measurements, research on various types of mineralization alteration information and systematic sample collection through geological surveys of inspection routes, and obtain preliminary prediction results of the intensity and scale of mineralization alteration. Sampling and testing; preliminary delineation of uranium polymetallic mineralization abnormal point zones to carry out abnormal inspection, comprehensive analysis to delineate favorable uranium and polymetallic prospecting prospects, and carry out engineering verification. This method can improve the efficiency of finding and evaluating uranium mineralization (abnormal) points, and can also take into account multi-metallic comprehensive prospecting and save tool expenses.

Description

technical field [0001] The invention belongs to the technical field of uranium ore geological exploration, and in particular relates to a uranium ore geological mapping working method for improving the efficiency of uranium polymetallic comprehensive exploration. Background technique [0002] Geological mapping of uranium mines is based on geological observation, and the service target is mainly the relevant basic geological information of existing mineralization, and its standards and quality are implemented in accordance with the geological mapping specifications of the corresponding scale. At present, the uranium mine geological mapping specifications mainly include 1:2000 and 1:10000 scales, and the smaller scales are carried out in combination with the reference regional geological survey specifications. Geological mapping of uranium deposits is based on basic geological mapping based on uranium deposit information. During the investigation and evaluation of uranium dep...
