Applications Of Simulation And Optimization Techniques In Optimizing Room And Pillar Mining Systems, Angelina Konadu Anani
Applications Of Simulation And Optimization Techniques In Optimizing Room And Pillar Mining Systems, Angelina Konadu Anani
Doctoral Dissertations
"The goal of this research was to apply simulation and optimization techniques in solving mine design and production sequencing problems in room and pillar mines (R&P). The specific objectives were to: (1) apply Discrete Event Simulation (DES) to determine the optimal width of coal R&P panels under specific mining conditions; (2) investigate if the shuttle car fleet size used to mine a particular panel width is optimal in different segments of the panel; (3) test the hypothesis that binary integer linear programming (BILP) can be used to account for mining risk in R&P long range mine production sequencing; and (4) …
Dynamic Impact Of Ageing Dump Truck Suspension Systems On Whole-Body Vibrations In High-Impact Shovel Loading Operations, Saeid R. Dindarloo
Dynamic Impact Of Ageing Dump Truck Suspension Systems On Whole-Body Vibrations In High-Impact Shovel Loading Operations, Saeid R. Dindarloo
Doctoral Dissertations
"Surface mining operations typically deploy large shovels, with 100+ tons per pass capacity, to load dump trucks in a phenomenon described as high-impact shovel loading operations (HISLO). The HISLO phenomenon causes excessive shock and vibrations in the dump truck assembly resulting in whole body vibration (WBV) exposures to operators. The truck suspension system performance deteriorates with time; therefore their effectiveness in attenuating vibrations reduces. No research has been conducted to study the impact of ageing suspension mechanisms on the magnitudes of WBV in HISLO operations.
This study is a pioneering effort to provide fundamental and applied knowledge for understanding the …
Subterranean Photobioreactors For Commercial-Industrial Scale Algal Culture, Daniel James Vidt
Subterranean Photobioreactors For Commercial-Industrial Scale Algal Culture, Daniel James Vidt
Doctoral Dissertations
"There are many potential benefits to the mining industry accruing from the application of algal biotechnology. The main benefits are in the production of biodiesel and in the remediation of mining brownfields. The research in this study was centered in the original idea that these brownfields represent a tremendous opportunity for use as a hybrid model for redevelopment into sustainable "mines" of biomass. The ability of these underground spaces serving as bioreactors to control all aspects of the growing environment, from lighting, to temperature, to biosecurity, are key advantages that have been identified in the literature. The many benefits inherent …
Cable Shovel Dipper Stress And Fatigue Failure Modeling In Formation Excavation Engineering, Muhammad Azeem Raza
Cable Shovel Dipper Stress And Fatigue Failure Modeling In Formation Excavation Engineering, Muhammad Azeem Raza
Doctoral Dissertations
"Large capacity shovels are used to achieve economic bulk production in surface mining operations. The suspended payload combined with dipper weight and formation resistive forces results in severe stress loading of the shovel front-end assembly. Material flaws, high stresses and harsh excavation conditions can initiate cracks in the dipper-teeth assembly. High stresses can cause these cracks to propagate to critical lengths resulting in fatigue failure, unscheduled downtimes, costly unplanned repairs, and downstream processing circuit problems. The literature reveals that dipper-related problems significantly reduce shovel up-time. This research is a pioneering effort towards developing a solid frame work for stress profiling, …
Modeling Explosive Lensing On A Cylindrical Body In Air: A First Step Towards Sealing An Underwater Offshore Oil Spill, Phillip R. Mulligan
Modeling Explosive Lensing On A Cylindrical Body In Air: A First Step Towards Sealing An Underwater Offshore Oil Spill, Phillip R. Mulligan
Doctoral Dissertations
"In 2010, the British Petroleum (BP) Deepwater Horizon accident leaked oil into the Gulf of Mexico for 87 days. A fast response method that can seal an oil pipe and stop the release of oil is needed in order to prevent future oil leaks from turning into ecological and financial disasters. Explosives can serve this need.
This research examined how a circular implosive discontinuous explosive lens interacts with a cylindrical surface. The following research was designed to study the applicability of the Method this author developed to predict the peak pressure from multiple shockwaves converging on a centrally located cylinder. …
