Backfill columns and the adjacent rock pillars at the underground backfilled stopes are not isolated but mutually supported. Stress transmission and energy alternation occur between them ceaselessly due to the ubiquitous mechanical interactions at the frictional-bonded interfaces between backfill...

This thesis describes several approaches evaluating the resistance of cement-based composites under adverse external-sourced sulfate attack. The conventional approach of evaluation by means of measuring expansion was discussed in comparison with the sulfate diffusion, which was quantified as a...

One of the essential components of the underground excavation design process, which directly influences the performance and stability of underground constructions, is knowledge of the in-situ and mining-induced stress. Knowing the magnitudes and directions of these stresses can help determine...

Erosion along the banks of the Brahmaputra River in Bangladesh and India leads to both the loss of infrastructure and land, consequently forcing many of those who live along the riverbanks into poverty. Because of the limited availability of hard materials that are traditionally used to protect...

Electric cable (or rope) shovels are critical equipment in the surface mining industry. An improved understanding of the factors that affect the flow of broken material into the dipper during loading can help to evaluate the performance of the excavator, define the criteria for equipment...

Geological heterogeneity is often represented by assigning rock properties to grids of different block size. Some geological features are represented as discrete objects at the chosen grid block size and others are represented as continuous properties. There is a transition between the discrete...

Hydraulic fracturing is a technique to enhance hydrocarbon production by inducing fracture(s) into reservoir rock. A fracture is induced by injecting fluid into the reservoir at pressures greater than the formation breakdown pressure. The fracture(s) geometry, mode, initiation and propagation...

Mining methods have changed and grown to fulfill extractive demands. Heavy machinery is used to extract overburden in open pit and open cast mines and to create waste dumps prone to slope stability issues. As the heaviest equipment operating on dump locations, mine haul trucks require a safe,...
