Hidden silicification fracture zone type uranium mine detection method

Abstract

A concealed silicification fragmentation zone type uranium mine detection method comprises the following steps: S1, setting survey points on the ground, and obtaining the U content and 210Po content of each survey point; s2, fitting to obtain a unary regression equation of < 210 > Po and U content, wherein < 210 > Po = aU + b; s3, the 210Po residual value of each measuring point is obtained, the 210Po residual value is equal to a 210Po analysis value and a 210Po theoretical value, the 210Po analysis value is obtained through field sampling analysis, and the 210Po theoretical value is obtained through a regression equation; and S4, obtaining an abnormal value in the 210Po residual value, and representing that uranium mineralization exists in the deep part. According to the method, the existing gamma energy spectrum measurement method and the 210Po measurement method are integrated, the purpose of judging the deep uranium mine distant view is achieved through the earth surface anomaly, engineering disclosure does not need to be conducted on a large number of earth surface anomalies, engineering disclosure can be conducted on the earth surface anomalies with the deep uranium mine distant view, targeted exploration is achieved, the exploration cost is saved, and the exploration efficiency is improved. And the prospecting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of energy detection, and in particular relates to a detection method for a hidden silicidation fracture zone type uranium ore. Background technique [0002] Uranium is a strategic energy resource. The silicification fracture zone type uranium deposit is an important type of uranium deposit, which is mainly distributed in South China and other regions in China. The silicification fracture zone type uranium deposit is mainly composed of granite, and the ore body is vein-shaped and lens-shaped. The shape and size of the ore body are related to the scale of the silicification fracture zone. The useful components of the ore are relatively simple, mainly of single uranium type. . [0003] South China is located in a subtropical climate zone, where vegetation is developed and the soil cover is thick. The silicification fracture zone is often fragmented and covered by the soil layer due to the geological tectonic ...

Problems solved by technology

[0004] Work experience tells us that although the above methods have discovered many silicified fractured zone-type or other types of uranium deposits, the prospecting efficiency is not high. These deposits are formed individually through the exposure and screening of a large number of surface anomalies or mineralization points one by one. , the proportion of surface anomalies or mineralization points developing into deposits may be less than 1%, wasting a lot of exploration and exposure workload
