Problems solved by technology

However, the occurrence conditions of these deposits are quite different, and the degree of exploration is different. There are differences in geological conditions, resource endowment, natural ecological environment, external supporting conditions, etc. of each deposit, which affect the The development plan, hydrometallurgy process, leaching mode, etc. of these sandstone-type deposits ultimately affect the economic benefits of deposit development

Embodiment Construction

[0092] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings.

[0093] This embodiment provides a comprehensive evaluation method for the development and utilization of sandstone-type uranium deposits, the process of which is as follows image 3 As shown, it includes two stages of conditional evaluation and comprehensive evaluation in turn, and the specific steps are as follows:

[0094] The first stage of conditional evaluation

[0095] Constraint evaluation refers to the evaluation of restrictive factors affecting the development of ore deposits. The conditional evaluation phase includes the following steps in sequence:

[0096] Step 1. Collect data on restrictive factors for ore deposit development; the restrictive factors in this embodiment mainly include the following three aspects: 1. In-situ leachability; 2. Environmental protection conditions; 3. Policy guarantees.

[0097] Step 2. Analyze the ...

Abstract

The invention belongs to the field of uranium mine exploitation technology, and particularly relates to a comprehensive evaluating method for exploration and utilization of sandstone type uranium deposit. The comprehensive evaluating method is characterized in that restraining factors which affect deposit evaluation are preliminarily screened through restriction evaluation, thereby preventing evaluation error caused by factors with one ballot veto in the deposit; quantification of sandstone type uranium deposit exploitation performance is realized through comprehensive evaluation; integral determining for the sandstone type uranium deposit exploitation effect can be realized; and instructive opinion can be supplied for exploitation decision of the sandstone type uranium deposit. The comprehensive evaluating method for exploration and utilization of the sandstone type uranium deposit has beneficial effects of comprehensive system, strict logic, accurate and reliable result, high applicability, etc. Integral evaluation can be performed on the ore deposit before construction of a mine, thereby preventing blindness in early-period exploration of the deposit, and reducing risk in deposit exploration.

Description

technical field [0001] The invention belongs to the technical field of uranium mining, in particular to a comprehensive evaluation method for the development and utilization of sandstone-type uranium deposits. Background technique [0002] For a long time, the research on the development of uranium deposits has mainly focused on mining technology, mine engineering, boundary optimization design, production management, etc., lacking a comprehensive evaluation of the internal and external factors of the deposit in the early stage of deposit development, resulting in development decisions. For example, due to a lot of preparatory work for the development of deposits with poor conditions in the early stage, construction or production has even started, but due to policy, environmental protection or external conditions, the later stage of production or production is restricted , it is difficult to achieve the expected economic effect, and finally caused huge waste of manpower and m...
