The influence of blasting on Kemess hypogene ore milling
Traditionally, optimization of drill and blast practices have taken place with sole respect to minimizing mine unit cost (as opposed to the operation as a whole), whilst maintaining fragmentation at a level that is considered ...
A Bayesian Approach to Convergence Detection in Underground Excavations using LiDAR
This thesis deals with the subject of convergence detection in underground excavations --- typically mining operations. Traditional methods for convergence monitoring involve operose surveying procedures that produce ...
Towards Estimating Friction Factors of Mine Drifts from Low Density Point Clouds
The standard for estimating roughness for the purposes of underground mine ventilation planning is to choose values found in a variety of textbooks that attempt to match the excavation type. These values are then used in ...
Automatic P-wave Picking of Microseismic Events in Underground Mines
This thesis investigates microseismic P-wave arrival time detection performance of automatic picking algorithms, as well as the handpicking performance of human experts. The data set used in this project was collected from ...
Stochastic Dynamic Optimization of Cut-off Grade in Open Pit Mines
Mining operations exploit mineral deposits, processing a portion of the extracted material to produce salable products. The concentration of valuable commodities within these deposits, or the grade, is heterogeneous. Not ...
THE INFLUENCE OF VENTILATION MODELING ON PRODUCTION PLANNING
Abstract The main objective of a ventilation system is to provide the quality and quantity of the airflows throughout the mine and to ensure safe and health conditions for the workers to the level specified by the mining ...
