The purpose of this thesis is to aid in the development of vertical cutting mining as a mining method. In order to do so, the technical feasibility and viability, and environmental benefit of vertical cutting as a complementary mining method were investigated. The investigation was performed for the case of the Victor Diamond mine in northern...

This thesis report presents a concept methodology to quantify the energy release associated with strain bursting in underground excavations based on the size of the failed zone and the elastic strain energy stored in the rock mass prior to failure. A strain burst implies potential harm to people and machinery and may lead to economic loss. An...

Significant part of geotechnical engineering projects involve the problems related to jointed rock
masses. For example, construction of tunnels in rock or stability analysis of the rock slopes. In this
framework, the finite element modelling is often used for problems with complex geometries or
where the analytical solution is...

Usually, oil fields are developed over three stages. First is the primary oil recovery, where the natural underground pressure is used to drive the oil to the surface. Afterwards is the secondary oil recovery, usually by water flooding or gas injection. However, the water flood yields lower sweep efficiency in heterogeneous reservoirs, contrary...

Rocking behavior of breakwater research was conducted by Centre for Civil Engineering Research and Codes workgroup CUR C70 (1989) and after that no further validation of the research work has been done. In order to understand the rocking behavior and validate the previously conducted research CUR C70 (1989) wave flume test has been conducted in...

Coda Wave Interferometry analysis is studied for rocks subjected to brittle deformation which is induced by an Uniaxial Compressive Strength testing machine. Ultrasonic pulses, 1 MHz and 2.25MHz, are sent through rock samples and recorded throughout the loading up-to failure. A novel method is proposed, the rolling cross correlation, which can...

Architectural engineering is evolving from a traditional craftsmanship to a new digital craftsmanship. Through advancements in production and processing techniques, we can achieve both mass production and offer mass customisation. As for the typology shown below, a simple house [1] & [2], the source of the material did not alter. The...

Momentarily the determination of the static stability of rock on mild slopes can be split in roughly two paths, the empirical and the physical approach. However, both the approaches have their limitations from which one could conclude that neither approach is currently an accurate description of the stability of rock on mild slopes under wave...

In the offshore industry rock is used for different kind of applications, such as scour protection and pipeline protection. In deep water operations, but also increasingly in shallow water operations, use is made of the method by guiding the rock from the water surface to the seabed with a fallpipe. During a rock placement operation a current...

Many authors already made an attempt to understand the effect of load-cycling on material strength and the evolution of elastic parameters. However, until now there was no study on the effect of load-cycling on the evolution of elastic parameters over the complete stress strain curve, i.e. the linear elastic regime, the fracturing regime, and...

The accurate estimation of the mechanical properties of a rock joints is crucial in terms of safety when it comes to design of slopes in open pit mines or caverns used for the storage of hazardous materials, for instance – nuclear waste. Photogrammetry provides a simple and objective method of joints roughness assessment, without the need for...

Postma, M.G. (author)
This study describes the stability of rock on a mild slope (e.g. milder than 1:6) under wave loading. This is done because an increasing number of situations occur where mild foreshores are protected from the wave and currents. The empirical stability formula, designed by VAN DER MEER [1988], is not valid for these kind of slopes. Nonetheless,...

In the last decades, measurement while drilling, or MWD, technology has set foot in the drill and blast tunnelling industry. Penetration rate, thrust, torque pressure, percussive pressure, rotation speed, water flow and water pressure are registered on a centimetre scale and processed to parameters more dependent on geology. These parameters...

Prototype single layer armour units on a breakwater slope are observed to break. To predict when breakage occurs, the objective of this research project is to obtain knowledge on, and measurements of the rocking behaviour and failure mode of single layer armour units. A single cube on a breakwater slope is subjected to investigations. An...

Quarry rock is a frequently applied construction material in hydraulic engineering. The main reason is its unique stability capacities in environments of high hydrodynamic activity. Furthermore, quarry rock is produced and handled relatively easily and available at numerous locations across the globe. The size, or more precisely, the dimension...

A lot of X-ray diffraction and X-ray fluorescence tests are performed in the department of Geoscience and Engineering to calculate a rocks likely ineralogical bulk composition. The old program used for this task was considered not user friendly enough, therefore an updating process of the old Mincomp program has been performed. During this...

Pipelines and cables on the sea bottom are usually protected by a cover of dumped rock. In case of maintenance or removal works, this cover has to be removed in order to expose the pipeline. This removal can be performed by means of a mass flow excavation process, created with a submerged jet flow. However, the exact erosion processes of a...

Low-salinity water flooding is a promising technique for the improvement of oil recovery. Despite intensive research, there are controversies about the pore-scale mechanisms behind the low-salinity effect (LSE). One of the proposed LSE mechanisms is wettability alteration, which is reflected in a decrease in contact angle. However, it is not...

This research focuses on the analyze of the heterogeneity of the Groningen gas field, i.e. characterization of the reservoir rock and the sealing Zechstein salt on top of the reservoir, by modeling the rock properties of the formations. The aim of this study is twofold, namely to characterize the thickness, shale content and porosity of the...

Low-salinity flooding (LSF) is an improved-oil-recovery method that consists of injecting brine with lower salinity than conventional formation water into the reservoir rock. This method has the potential to improve the oil recovery beyond conventional waterflooding. In sandstone reservoir rocks, it has been reported that the salinity range...
