The included area of each triangle is assigned the characteristic not of a single hole, but of the weighted average of the three holes forming the triangle. The weighting of the three holes is based on the length of the drill holes. Triangular method is and extended approach of the polygon method. To determine the extent of the deposit, triangles are developed such that sampling points form the apices of the triangles. The volume and tonnage of the deposit is then determined using simple geometrical equations. 1.

Nov 23 2003 · be consideredinclude mining metallurgy geotechnical hydrological environmental location marketing legal requirements revenue costs and social implications 7 Mineral Reserve Estimation A Mineral Reserve estimate represents the collation of work carried out by numerous professional disciplines and Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model.

A short summary of this paper. For reserve estimation volume and density parameters must be included into calculations. To include the volume parameter into calculations the width of a block (on XY plane) must be obtained.

Playing off the triangular shape of the plot, the single-storey dals långed dating Triangular method By using triangular method, the area of the ore body is calculated After that, this calculated area is multiplied with average thickness of the ore to calculate the volume of the ore body The average thickness can be calculated by Using known thickness of the ore body Using grade and the length of ore body Using weight age average thickness After calculating volume, multiplying this value with ore density to estimate the ore reserves. In the first case, the triangular or polygonal prism method may be employed for computing tonnages and grades of ore. The global resource calculated for the Minetechpg copper deposit using triangular method is 142,545 tons (extent/size) ore at an average grade of 6.75% (value) Copper. In conclusion, the tonnage and grade determined using the two methods is approximately the same. Find out information about triangular method.

A method of ore reserve estimation based on the assumption that a linear relationship exists between the grade difference and the distance between all drill
Another method, known as the triangle method, requires that we connect adjacent holes into triangles. The included area of each triangle is assigned the characteristic not of a single hole, but of the weighted average of the three holes forming the triangle.

This research was supported in part by.the Energy Research and. CP by SRK consulting, resource and ore reserve estimations were carried out in GFGL Tarkwa The methods used to estimate reserves also developed, or by triangulation of a series of points and strings into a digital terrain model, m Database, and were also used in the minable ore reserve estimation. By using the above mentioned data, the ore thickness (m) was finalized by hand method. The Triangular Method Reference.

Definition of triangular method A method of ore reserve estimation based on the assumption that a linear relationship exists between grade difference and the distance between all drill holes. resource estimation methods (e.g. polygonal, triangular, random stratified grids (RSG), or cross-sectional methods) rely on a few simple parameters, such as area, thickness and grade (based on chemical assay data).

6.75%. The global resource calculated for the Minetechpg copper deposit using mineral reserves estimation by using triangular method. november 2020; doi: 10.13140/rg.2.2.26999.44968 Value and extent of a mineral deposit can be estimated using classical methods or geostatistical Geostatistical methods employed for ore reserve estimation utilize three-dimensional spatial statistics to improve the quality of the estimate. Classical statistics requires use of a particular distribution model, e.g., the data are normally distributed, and that the samples be independent of one another.
