Reserve Estimation Methods Pdf Contour Line Mining The document discusses principles and assumptions for estimating ore reserves and grades. it describes two key principles: 1) the rule of gradual change, which assumes grades change gradually between known points, and 2) the rule of nearest points, which assumes unknown points take the value of the closest known point.

Ore Reserve Estimation Method 911 Metallurgist Pdf Triangle Area Estimation and mine planning principles and are designed to provide general guidelines of best professional practices employed in the preparation of mrmr estimates. although the 2019 mrmr best practice guidelines are intended for use by canadian based mining exploration practitioners , many of the. A catalogue record for this book is available from the british library. We conducted a detailed comparison of model outputs with data from actual mining sites where the quantities of extracted ore were measured. this empirical validation approach follows the methodology suggested by davis (2018), who emphasized the importance of real world data validation in predictive model assessments. Monte carlo techniques are used to construct the initial distribution of potential reserves in a reservoir. although definitions and use vary, general use is that proven reserves (1p) represents a 90 % certainty level; proven probable (2p), a 50 % certainty level; and proven probable possible (3p), a 10 % certainty level (figure 2).

The document provides an overview of classical ore reserves estimation methods. it discusses key definitions and requirements for ore reserve methods including being geology controlled, simple, robust, understandable, consistent with data density, and realistically reflecting the mining method. The document discusses principles and assumptions for estimating ore reserves and grades. it describes two key principles: the rule of gradual change, which assumes grades change gradually between known points, and the rule of nearest points, which assigns values to midpoints based on the nearest known point. The reserve estimation is quantification of economic material present in the ore body with reasonable accuracy. it also involves computation of grade, thickness and different qualitative parameters which are required for commercial exploitation of the ore. In planning, implementing, and directing any mrmr estimation work, the practitioner(s) should ensure, to the extent practicable, that the estimates are prepared using sound evaluation practices, sound estimation and scientific principles, and according to good mining practices. they should also ensure.
