Open-pit mine planning with operational constraints
Open-pit mines must be designed to develop the Earth’s natural resources in the most responsible, sustainable, and economic way. Traditional mine planning optimization methods do not consider operational constraints; such as minimum mining width or minimum pushback width constraints, and often do …

Remote sensing analyses for open pit mine area computation. A comparative study on the implementation of multi-spectral classifications and crowdsourcing to compute the spatial extent of four open-pit mines in Indonesia, Australia, Canada and Brazil
… have already been conducted in the domain of mine detection and mapping, no comparative study has yet been carried out that investigates several remote sensing analyses, which are transferable to other geographic regions. The aim of this study is thus to compare remote sensing analyses that …

Pre-Feasibility Study of a Diamond Mine
… develop the property into an operating diamond mine. This recommendation is based upon the discounted cash flow analysis, using a discount rate of 8 percent. Based on this analysis the property has a Net Present Value (NPV) of $15.189 billion and an Internal Rate of Return (IRR) of 121 percent. …

Resource Debate in Southwest Alaska: The Bristol Bay Fishery and the Pebble Mine
… a plan to develop a low-grade, but substantial, mineral deposit that consists primarily of copper, gold, and molybdenum. The estimated value of the minerals present is more than $500 billion. This plan is known as the Pebble Project, and could involve an open-pit mine, a large area of block …

An application of 3-D modeling and optimization of the final pit limits for a lignite deposit
… algorithms have been developed in order to determine the optimal final limits of an open pit mine. Due to the complex nature of this problem, however, very few of them can offer a reliable and complete answer. The case of an actual lignite deposit was used in this study, which enabled an …

Multi-body dynamic and finite element modeling of ultra-large dump truck - haul road interactions for machine health and haul road structural integrity
… their economies of scale in large-scale surface mine production systems. Ultra-large trucks impose high dynamic loads on haul roads. The dynamic loads are exacerbated by road surface roughness and truck over-loading. The dynamic forces also subject trucks to high torsional stresses, which affect …

Fracture reactivation and gold mineralization in the epithermal environment : structural evolution of the Endeavour 42 gold deposit, New South Wales, Australia
The development of an open pit mine at the Endeavour 42 (E42) epithermal gold deposit, situated in the Junee-Narromine Volcanic Belt of the Ordovician Macquarie Arc, central New South Wales, has provided a 3D view of the structurally controlled deposit which was hitherto not available due to the …

Exhibition Center on the Stone Quarry
… studying. A quarry in Blacksburg, Virginia, an open-pit mine where dimension stone, sand, gravel and slate were excavated, provided me with an opportunity to explore this idea. The building I designed would help to display the original state of this old quarry, now half-filled with water. I …

Transportation system selection in open-pit mines (Truck-Shovel and IPCC systems) based on the technical, economic, environmental, safety, and social (TEcESaS) indexes
… is known as the conventional transportation in open-pit mines, which is preferable because of the low capital cost and high flexibility, it still imposes a high rate of operating costs, safety issues as well as environmental footprints. In-Pit Crushing and Conveying (IPCC) systems are the …

Improving Health and Safety at Surface and Underground Mines by Implementing Emerging Technologies Coupled With Geotechnical and Climatic Modeling
… health and safety focus for modern underground mines involves improving the subsurface thermal climate through modeling and the use of waste heat. The health and safety focus for surface mines can relate to the slope stability and highwall management utilizing slope modeling and data analysis to …
