For the purpose of production scheduling, open-pit mines are discretized into three-dimensional arrays known as block models. Production scheduling consists of deciding which blocks should be extracted, when they should be extracted, and what to do with the blocks once they are extracted. Blocks that are close to the surface should be extracted first, and capacity constraints limit the producti...

One of the key issues in mining is the hauling system. Truck and shovels are the most widely used transportation equipment in mines. In this paper, a two-phase simulation-based optimization is presented to maximize utilization of hauling system in the largest Iranian open-pit copper mine. In the first phase, The OptQuest for Arena software package was used to solve the optimization problem to p...

For the purpose of production scheduling, open pit mines are discretized into threedimensional arrays known as block models. Production scheduling consists in deciding which blocks should be extracted, when they should be extracted and how each extracted block should be processed. Blocks which are on top should be extracted first, and capacity constraints limit the production each time period. ...

Planning and design procedure of an open pit mining project just can be started after ultimate pit determination. In the carried out study in this paper it was shown that the most important factor in ultimate pit determination and in consequence in the whole planning and design procedure of an open pit mine is the metal price. Metal price fluctuations in recent years were exaggerated and impose...

Optimisation tools which determine the best layout for access and haulage in an underground mine address an important and difficult mine design problem. The complexity of the problem can be compared to the task of optimising the final pit design in an open pit, together with the pit haul roads required. The strategic design of an underground mine layout must address the location of haulage shaf...

A dynamic optimization method was created to address the production schedule issue in an open-pit coal mine while taking into account characteristics of fuzzy structured element. The mining capacities all “geologically optimal push-back bodies” were then examined using moving cove method. One most crucial elements process scheduling is pricing. As a result, this work also presents technique for...

Based on current researches and developments of open-pit mine slope in China, the engineering features of open-pit mine slopes are summarized. Mine slope is basically formed by dynamic excavation of multi-level and multi-type, and mining benefit is the purpose of mine slope engineering when using various schemes and/or methods. Thus, the issues of design and stability analyses are the main conc...
