Problems solved by technology

However, it has to be pointed out that the methods mentioned above are all indirect prospecting methods except the diffusion extraction method and the salt ion complex prospecting method, which consume a lot of manpower, material resources and financial resources, and the cost is high.
Although the salt ion complex prospecting method, diffusion extraction method and gas ion state method invented in Russia can discover hidden uranium deposits below 400 meters deep, they have not been widely used in my country due to limited use conditions and high costs.

Embodiment Construction

[0063] The Kujieertai sandstone uranium deposit is located between Honghaigou and Kujieertaigou, Qiongbola Township, Qapqal County, on the north slope of Ketemin Mountain.

[0064] The deposit is produced in the clastic rocks between the first coal seam roof and the eighth coal seam floor of the Shuixigou Group of the Middle and Lower Jurassic. The ore body is lenticular and dovetail-shaped, with a buried depth of more than 100 meters or 200. Meter.

[0065] Carry out PMBP and N263 foam plastic surveys on the 20th line of this mining area, with a point distance of 100 meters.

[0066] The results of the investigation on the adsorption of PMBP foam plastic are shown in Table 1 and figure 1 Shown. The known No. 1 (Th+U) anomaly is confirmed by known ore bodies.

Abstract

The present invention relates to the ore prospecting of blind uranium ore deposit and is one foamed plastic carried extraction and exploration method. Foamed high density polyurethane plastic carrying PMBP or N263 with very high adsorption to uranium (VI) is used as extracting material in adsorption extracting exploration or constant-voltage adsorption extracting exploration. The said method can find uranium ore deposit buried deep under to 400 m depth, and the present invention solves the difficult problem of finding blind uranium ore deposit. The present invnetion includes the preparation of foamed plastic carrying PMBP or N263 and field extraction job. The present invention has the features of great information amount, high abnormal peak, great enrichment coefficient and good ore finding effect.

Description

Technical field [0001] The invention relates to a concealed uranium deposit prospecting and exploration method; specifically, it relates to a loaded foam plastic extraction and exploration method. Background technique [0002] The concealed uranium deposit prospecting method has always been a key technical problem that puzzles the development of my country's nuclear industry. In the past, my country used traditional geophysical and geochemical survey methods, such as the soil secondary halo measurement method, activated carbon adsorption method, potentiometric measurement method, and geophysical exploration excitation method, transient electromagnetic method, and even geochemical exploration. Low-frequency measurement method and gamma spectrum measurement of radioactivity measurement, etc. The above-mentioned geochemical exploration methods have little or no prospecting effect for the general prospecting of deep-producing concealed uranium deposits, because the amount of informat...
