Given a block-model of an open cut mine, a production scheduling policy defines which blocks should be extracted, when they should be extracted, and what should be done with them once extracted (i.e., sent to a mill, waste-dump, stockpile, etc.). The conventional three-step heuristic for constructing such a scheduling is as follows: First, compute an ultimate-pit. Second, subdivide the ultimate...

One of the most critical aspects open pit mining is dewatering and mine drainage systems. The NCP Open Pit Gold Mine located in Central Kalimantan. This study area has a range rainfall intensities durations from moderate to heavy. Good required manage runoff water reduce entering front loading. used daily intensity data 1994 2018. Using Mononobe Method, hydrological for this were evaluated by d...

Driverless haulage trucks have recently been developed for open pit mines. To predict the benefits of an Autonomous Haulage System (AHS), a deterministic/stochastic model has been created to compare AHS to a manual system by estimating benchmarked Key Performance Indicators (KPIs) such as productivity, safety, breakdown frequencies, maintenance and labor costs, fuel consumption, tire wear, and ...

In the context of open-pit mine planning, uncertainties including commodity price would significantly affect the technical and financial aspects of mining projects. A mine planning that takes place regardless of the uncertainty in price just develops an optimized plan at the starting time of the mining operation. Given the price change over the life of mine, which is quite certain, optimality o...

Many coal mines are being abandoned for economic and environmental reasons in China. The repurposing of open-pit into pumped storage hydropower (PSH) can help with the renewable energy, improve mine environments, provide added value. Construction PSH plant will change water level pit, which is envisaged as lower reservoir, thus influencing slope stability. In this study, Fushun West Open-Pit wa...

A vehicle proximity warning collision avoidance system is being developed using GPS and wireless local area networks to improve safety of off-highway trucks in open pit mines. After two an a half years of research, software development, and laboratory testing, field tests were carried out at operating limestone quarries and open pit mining operations to evaluate GPS accuracy and overall system ...
