Open-pit mining is an operation in which blocks from the ground are dug to extract the ore contained in them and in this process a deeper and deeper pit is formed until the min-ing operation ends
The Lerchs-Grossmann LG algorithm 1965 has been used for over thirty years for the optimum design of open pit mines. This has been combined with variable grade cutoff and discounted cash flow

2019-2-13Wireless Telemetry System Streamlines Water Distribution System of Open Pit Mining Operation Application Story APPLICATION A mining company experienced problems when manually monitoring water flowing through a pipeline system that supported its open pit mining operations. Workers would travel along the waterline that enveloped mountains at a
Production scheduling is a critical activity for the long-term production planning of open pit mining operations. It deals with the effective management of resources and maximies cash flows to generate higher profits over the life of a mine. Production scheduling problems determine that blocks be mined and processed over a number of periods subjected to mining and processing constraints
2020-5-8The December 2014 N.I. 43-101 Pre-Feasibility Study demonstrated an open pit mineral reserve of 675k ounces of gold that could produce 79000 ounces annually over 8 years at all-in sustaining costs
Declining trends in average ore grades increasing mining costs and environmental considerations will ensure that this situation will remain in the foreseeable future. The operation and management of a large open pit mine having a life of several 550 years is an enormous and complex task

2020-4-13The open-pit mining problem is to determine the contours of a mine based on economic data and engineering feasibility requirements to yield maximum possible net income. This practical problem needs to be solved for very large data sets. In practice moreover it is necessary to test multiple scenarios taking into account a variety of realiations of geological predictions and forecasts of
