Abstract:

Spatial heterogeneity of the environment, as measured by floral diversity, composition and structure, is known to influence the distribution and diversity of invertebrates. Heterogeneity brought about by anthropogenic disturbance may be a threat to invertebrate diversity. This thesis investigates the impacts of vegetation heterogeneity at a range of scales on the diversity of invertebrate populations in modified high-altitude indigenous grasslands on the Rock and Pillar Range, Central Otago. Invertebrates were sampled in and on the edges of snow tussock fragments to assess whether species ri

Abstract:

The company Rio Deserto is currently mining the famous Barro Branco coal seam in the state of Santa Catarina located in the south of Brazil. One of their coal mines, #101, is experiencing problems related to the pillars in one panel. The coal seam is slightly inclined and several pillars have developed damages on the down-slope side with focus in the top corner. Damage inspections revealed a thin clay layer located between the coal pillar and the overlying siltstone. The clay layer is believed to affect the pillar strength and possibly be a source for the observed damages. Aim of this report h

Abstract:

The geological disposal of nuclear waste, in underground openings and the long-term performance of these openings demand a detailed understanding of fundamental rock mechanics. A full scale field experiment: Äspö Pillar Stability Experiment was conducted at a depth of 450 m in sparsely fractured granitic rock to examine the rock mass response between two deposition holes. An oval shaped tunnel was excavated parallel to the σ3 direction to provide access to the experiment and also provide elevated stress magnitudes in the floor. In the tunnel floor two 1.75-m diameter 6-m deep boreholes were ex

Abstract:

Highwall mining is a mining method used in surface coal operations that involves driving a series of parallel entries into the exposed coal seam at the highwall face under an unsupported roof leaving behind a series of long, but very slender coal pillars. Highwall mining often occurs simultaneously with production blasting taking place in other areas of the mine. Although no failures of highwall pillars have been attributed to nearby blasting, numerical modelling presents an inexpensive means of investigating the possible effects of strong ground motion on the stability of these pillars.

Abstract:

This thesis deals with the problem of applying computer vision techniques in an underground mine environment. In particular, the problem of the localization and identification of oversized rock fragments prior to secondary breakage, following the initial drilling and blasting operation is addressed. The strategy employed is based on the methodologies developed for reconstruction and interpretation of range image data. Discrete rock pile images acquired using the NRCC/McGill laser rangefinder were used in this study. The main contribution of this thesis is the complete study of the paradigm whi

A detailed structural study of Rock Canyon (near Provo, Utah) provides insight into Wasatch Range tectonics and fold-thrust belt kinematics. Excellent exposures along the E-W trending canyon allow the use of digital photography in conjunction with traditional field methods for a thorough analysis of Rock Canyon's structural features. Detailed photomontages and geometric and kinematic analyses of some structural features help to pinpoint deformation mechanisms active during the canyon's tectonic history.

High voltage breakage is a relatively novel comminution technology that uses highly energetic electrical discharges to induce electrical breakdown in rocks. Advantages of the technology in terms of weakening of rocks to ease comminution, as well as improved liberation compared to mechanical fragmentation methods have been demonstrated. However, a detailed understanding of the fragmentation mechanism and its selectivity, as well as how to optimise the process in terms of efficiency and treatment outcomes was still lacking prior to this thesis.

The Hurricane Fault is a 250-km long, west dipping, Basin and Range-bounding normal fault in SW Utah and NW Arizona that initiated in the mid-Miocene to Pliocene. It has been primarily active in the Quaternary, with slip rates of 0.2 – 0.6 mm/yr. There are multiple hot springs along its 250-km length and multiple late Tertiary-Quaternary basaltic centers broadly parallel the fault. Possible sources of hot spring fluids include deeply-circulated meteoric water that experienced water-rock exchange at high temperatures (>100 °C) and deep-seated crustal fluids.

The evolution of mountain landscapes is controlled by complex interactions between large-scale tectonic, surficial and climate conditions. Dominant processes are attributed to creating characteristic features of the landscape, but topographic features are the cumulative result of coupled surficial processes, each locally effective in a different climate or elevation regime. The focus of erosion by glacial, fluvial, or mass wasting processes is highly sensitive to small changes in boundary conditions, therefore spatial and temporal variability can be high when observed over short time scales.

Abstract:

Eliot Glacier is a small (1.6 km2), relatively well-studied glacier on Mount Hood, Oregon. Since 1901, glacier area decreased from 2.03 ± 0.16 km2 to 1.64 ± 0.05 km2 by 2004, a loss of 19%, and the terminus retreated about 600 m. Mount Hood's glaciers as a whole have lost 34% of their area. During the first part of the 20th century the glacier thinned and retreated, then thickened and advanced between the 1940s and 1960s because of cooler temperatures and increased winter precipitation and has since accelerated its retreat, averaging about 1.0 m a-1 thinning and a 20 m a-1 retreat rate by 2004

From Ancient Near Eastern texts, the Bible and archaeological artefacts, we are able to glimpse an over arching belief in a feminine deity.
