Verhoeff, R.L.A. (author)
Mine design and mine planning are essential to a mining operation as they do not only dictate the outline of the mine, but essentially determine the financial robustness and success of the mining operation. However, as mining is a conservative business mine design is still mostly done by hand. To indicate the effect of uncertainty in mine design...

Sensor Based Sorting can decrease the amount of material processed in the subsequent processing steps, by separating the valuable material from the invaluable material, and therefore potentially reducing costs in those subsequent steps. For sensor based sorting to be effective, a strong relation needs to be present between the properties...

Diatomite is a white and soft sedimentary rock made of the skeletal remains of diatoms. Diatoms are unicellular organisms that belong to the algae and have a skeleton made of opal (hydrated silica). The ore in the deposit in Elche de la Sierra (Spain) is primarily made of these diatoms but there is also calcium carbonate present in the ore. The...

The potential emergence of mining seafloor massive sulphide deposits make it necessary to assess the economic feasibility of these deposits. In this thesis it is suggested that a series of calculations can be used to increase the level of confidence from a geological occurrence to an ore reserve. An analysis has been done on uncertainties that...

Optimization in the mining industry is often only done on a discontinuous and long-term basis. The RTRO-Coal project aims to improve the mining efficiency by introducing a continuous optimization cycle. As a part of the RTRO-Coal project, an experimental simulation model, validated in the lab (TRL 4), for short-term mine optimization was...

This thesis is conducted for Royal IHC and Witteveen+Bos. Royal IHC is a Dutch ship builder and Witteveen+Bos an engineering consultant. Both companies have encountered the problems of water hyacinth. Water hyacinth, Eichhorni Crasippus, is an aquatic weed which is widespread throughout the tropics and subtropics. It is an invasive species in...

Bentonite is a clay that is used in many industrial applications. Company X required an investigation on the bentonite that is mined by Company Y. Currently Company X produces cat litter only from her bentonite, but other applications might be of economical interest to the company. After scoping down to 4 applications other than cat litter ...

This Thesis carried out research towards development of a coal quality concept on geological and mining engineering operational level of Mátrai Er?m? ZRt’s Visonta and Bükkábrány open cast lignite mines, with objective to reduce and avoid sub-optimal combustion behaviour at Mátra Power plant. RWE Power AG is the major shareholder of Mátrai Er?m?...

A desire for increased recovery in highwall mining has fueled an interest into the possibility of applying backfill technology to highwall mining. Backfill technology offers the potential for additional advantages, including increased stability and profit. This technique is currently applied in underground mines, but has not yet been implemented...

Markesteijn, M. (author)
The copper grade in the Aitik mine in northern Sweden is decreasing, therefore other deposits are investigated. One of these deposits is the satellite deposit discussed in this thesis. The grade of this deposit is higher than in Aitik and could thus be used to increase the copper production at the Aitik mine site. The goal of this thesis is to...

Because of high resource prices for rare earth elements over the last decade, companies and governments are investing in research in finding new deposits and innovations. The purpose of this thesis is to measure the potential of rare earth deposits in the deep-sea environment. This is done by a wide and extensive literature study with a focus on...

Blast fragmentation has an influence on the drill and blast designs, loading, hauling and crushing operations. Previous studies in other mines have shown that by optimizing fragmentation it is possible to save on operational costs. This thesis investigates and applies a method for measuring fragmentation in stopes with the aid of image analysis...

The aim of this research project was to introduce and evaluate an optimization approach for sublevel stope mine optimization using the AMIRA Stope Optimizer that includes grade-risk quantification and can be used by Boliden engineers for future mine planning and economic assesment. It has long been realized that mining simply every part of an...

The use of sensor measurement data in mines today is usually limited to the downstream processing of mined material in a feed-forward loop. This thesis investigates the capability of Kalman Filtering techniques in updating resource models, based on sensor data, in a feed-back sense. The mining operation and updating process are simulated in...

For the construction of breakwaters large amounts of armourstone which are produced in dedicated quarries are needed. The better the in-situ block size distribution (IBSD) of these quarries can be determined, the more accurately the quarry production can be predicted. Currently, the IBSD prediction is based on manually acquired scanline data....

Mining is different from most businesses because knowledge of the product is essentially based on estimates, which by their very nature include a degree of uncertainty (Dominy, Noppé, & Annels, 2004). The risks associated with mining are varied and complex, where the dominant source of risk is the orebody itself (Snowden, Glacken, & Noppé, 2002)...

Mining method selection lies at the basis of every mining operation and is essential for maximizing economic return. Especially in the current market with decreasing metal prices selecting the right method can mean the difference between a viable and a non-viable operation. More importantly the right mining method increases the safety of...

In this study a cash-flow analysis is done in order to establish the cash sources and sinks of a peer group of mining companies in the iron ore sector. The peer-group ranges from junior companies to major mining companies. The study also looked in to the performance and profitability of the peer group using ROCE and share prices as indicators....

Cave mining operations produce bulked ore from self-sustainable propagating caves in high stress regimes. Undercut development creates even higher abutment stresses and a stress-shadow which have significant impact on extraction level stability. Geotechnical assessment of the infrastructure is vital for the safety performance and continuity of...
