Problems solved by technology

Moreover, the "F-value method" believes that "the trapezoidal volume of ore blocks can also be calculated by the F-value method", which misleads the mineral reserve calculation personnel, regardless of the nature of the ore blocks, and all without distinction are calculated using the "F-value method" The volume of the ore block is obviously not scientific enough
Because there is a big difference between the truncated cone volume formula and the trapezoidal volume formula, the functions in the field of mathematics are clear and rigorous, and cannot be mixed or replaced

Embodiment Construction

[0060] According to the different properties of the ore blocks, the present invention adopts different calculation formulas—a truncated cone volume formula and a trapezoidal volume formula—to simplify, and lists the A value and its corresponding K value respectively to form a corresponding table of A and K values. Prerequisites for specific applications are:

[0061] 1. When the relative area of ​​ore bodies on two adjacent sections is different: , use the trapezoidal formula: Calculate the block volume.

[0062] 2. When the relative area of ​​ore bodies on two adjacent sections is different: , use the frustum formula: Calculate the block volume. because

[0063] or

[0064] The specific simplification principles and methods are as follows:

[0065] The formula for the volume of a truncated cone is:

[0066] In the formula: V - ore block volume (m 3 )

[0067] S 大 , S 小 -The area of ​​the upper and lower bottom of the ore block (m 2 ), where S 大 >S 小 ...

Abstract

The invention relates to a simple ore block volume calculation method for calculating mineral resource reserve. According to different ore block properties, different ore block volume calculation formulas, i.e. a truncated cone volume or trapezoid volume simplified formula, are adopted, and according to calculated value A and corresponding value K, an A-K value correspondence table is prepared. Consequently, the troublesome, time-consuming and tedious work is simplified into convenient, quick and labor-saving work, the working efficiency can be increased by multiple times,the error is less, the precision is high, the requirement on the precision of mineral resource reserve calculation can be fully met, and moreover, the problem of misuse in the process of mineral resource reserve calculation can be completely avoided. The method can be used by the mining geology department, the geological prospecting department, the mine design department and other departments to calculate mineral resource reserve.

Description

technical field [0001] The invention belongs to the field of mineral resource reserve calculation, and relates to a table for simplifying ore block volume formulas and listing the simplified calculation A and K values ​​of the ore volume formulas (hereinafter referred to as A and K values) in the calculation process of mineral resource reserves. Correspondence table), so as to quickly obtain the simple calculation method of the calculation result. Background technique [0002] One of the final results of geological exploration is to accurately calculate and find out the reserves of underground mineral resources. The amount of reserves is one of the important bases for determining the scale of mine construction and the investment budget for mine construction, and it is also the assessment content for determining the economic benefits of mining. [0003] Therefore, geological prospectors and mine geologists have attached great importance to the calculation of reserves of mine...
