Orebody Modelling and Strategic Mine Planning - Uncertainty and Risk Management Models

Description

Orebody modeling and strategic mine planning are arguably the backbone of the industry and represent an intricate, complex and critically important part of mining ventures. They have a profound effect on the value of a mine, as well as determining the technical plan to be followed from mine development to mine closure. This second edition includes three additional papers highlighting new developments, including integrated mine evaluation and mine management under uncertainty; optimizing ore extraction and in-pit dumping; and stochastic simulation of orebody geology or wireframes with multi-point spatial statistics. Topics covered include: Why Strategic Risk Management? New Practical Conditional Simulation Methods and Applications Advances in Conventional Mining Optimization and Applications Integrated Large-Scale Applications Geological Uncertainty and Mineral Resources/Ore Reserves Geotechnical Risk and Mine Design Case Studies and Blending Optimization New Concepts, Technologies and DirectionsContent: Front Matter • Table of Contents •Section 1.
