Problems solved by technology
my country's hard rock uranium mines have the characteristics of complex geological structure of deposits, small ore bodies, large changes in shape and grade, unclear boundaries of ore rocks, requiring geophysical prospecting to find edges, short shift working hours, and low work efficiency
The current production scale calculation formula used in the design of metal mines is mainly based on the characteristics of metallurgical mines, non-ferrous mines and gold mines. It is not suitable for uranium deposits. It is difficult for the actual production scale to reach the design scale. This will not only delay production, but also waste a lot of money, and thus affect the economic benefits of the enterprise and the country's natural uranium production plan

Embodiment Construction
[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0044] Such as figure 1 As shown, a method for determining the production scale of a hard rock type uranium mine, the method specifically includes the following steps:
[0045] Step 1. Utilize the existing geological exploration data of ore deposits to obtain the corresponding mine mining reserves;
[0046] Step 1.1, collecting the geological exploration data of the deposit whose production scale is to be determined, and obtaining the geological resource reserves of the deposit;
[0047]Collect and obtain geological exploration data of deposits with a production scale to be determined, and obtain proven and controlled economic basic reserves and intrinsic economic resources in the main types of resource reserves. The inferred intrinsic economic resources can be partially used; the inferred intrinsic economic resources The reliabilit...

The invention relates to the technical field of determination of production scale of a hard rock type uranium mine, and concretely discloses a method for determining the production scale of a hard rock type uranium mine. The method comprises the following steps of 1, using the existing ore deposit geological exploration information to obtain corresponding mine stoping reserves; 2, determining a mine vertical annual descending rate according to the ore deposit ore body characteristics; 3, using the existing ore deposit geological exploration information to obtain a mine stoping space height; and 4, determining and obtaining the production scale of the mine according to the mine stoping reserves, the mine vertical annual descending rate and the mine stoping space height obtained in the steps. The method for determining the production scale of the hard rock type uranium mine has the advantages of few related parameters, simple and convenient calculation, reliable result and the like. A reasonable production scale model of the uranium mine can be built; the determination on the scale of the hard rock type uranium mine is realized; and the reference is provided for the mine developmentand utilization.
Description
technical field [0001] The invention belongs to the technical field of determining the production scale of hard-rock uranium mines, and in particular relates to a method for determining the production scale of hard-rock uranium mines. Background technique [0002] my country mainly adopts the calculation method of the former Soviet Union to determine the production scale of metallurgical mines. However, due to my country's poor resource conditions, low management level, and backward mining technology and mining equipment, many mines that have been in operation for many years have not been able to reach production, or even can only reach the design. half the size. Summarizing domestic research results, there are mainly four different ways to determine the scale of mine production: technical analysis, economic analysis, statistical analysis and comprehensive factor analysis. The calculation methods for determining the production scale of mines in domestic metallurgical pits ma...
