Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0021] Such as figure 1 As shown, a method for determining the production scale of an in-situ leachable sandstone-type uranium deposit specifically includes the following steps:
[0022] Step 1. Obtain the amount of geological resources based on the collected geological survey data, and calculate the amount of resources used by the mine;
[0023] Collect geological and hydrogeological data to obtain the amount of geological resources B. After verifying the amount of geological resources B using the degree of geological exploration, multiply the amount of geological resources B by the utilization coefficient λ to obtain the amount of mine utilization resources P. Among them, the utilization of mine resources The coefficient λ ranges from 0.5 to 1, and the specific value is determined comprehensively according to the degree of exploration of the deposit a...

The invention relates to the technical field of uranium ore geological exploration, and specifically discloses a method for determining the production scale of an in-situ leachable sandstone-type uranium deposit. The method specifically includes: 1) According to the collected geological exploration data, the amount of geological resources is obtained, and the resource amount P used by the mine is calculated; 2) According to the geological exploration data, the data of the uranium amount per square meter is obtained, and the correction factor of the uranium amount per square meter is finally determined K p ;3) Obtain permeability data according to geological exploration data, and finally determine permeability correction coefficient K s ; 4) According to the amount of mine utilization resources obtained in steps 1 to 3, the correction coefficient of uranium per square meter and the correction coefficient of infiltration, the production capacity of the mine is obtained; a method for determining the production scale of an in-situ leaching sandstone-type uranium deposit according to the present invention, The production scale of the mine can be obtained through the actual uranium content per square meter and the permeability coefficient of the in-situ leaching mine, and the method has strong applicability, accurate results, simplicity and reliability, and can provide a reference for the development and utilization of the mine.
Description
Technical field [0001] The invention belongs to the technical field of uranium mine geological exploration, and specifically relates to a method for determining the production scale of an in-situ leachable sandstone type uranium deposit. Background technique [0002] At present, the method for determining the production scale of in-situ leaching uranium deposits at home and abroad is relatively complicated. Usually, it is necessary to obtain permeability coefficient, reagent unit consumption, single hole extraction volume, average uranium concentration of leaching solution, etc. through indoor cups, field conditions and industrial tests. After the parameters, it is determined comprehensively according to the reserves of the ore deposit, the conditions of the ore body, the natural and socio-economic conditions of the site. Obviously, it is unrealistic to use this set of procedures to determine the production scale of each deposit in the technical and economic evaluation and classi...
