Course description. Underground mining methods and equipment for bedded deposits and ore bodies; de-scription and selection of mining methods, equipment requirements …
appropriateness of a mining method for a particular ore deposit have been in use for some time. In 1981 Nicholas suggested for the first time a numerical approach for mining method selection. The Nicholas methodology follows a numerical approach to rate different mining methods based on the rankings of specific input parameters.

First, a rational selection of the four best-ranked mining methods for underground mining is performed using numerical methods (Nicholas' approach and the modified approach of Nicholas, i.e., UBC ...
Loading tool selection guide 6 Electric rope shovels: overview An electric mining shovel, often referred to as a mining rope shovel or an electric rope shovel, is designed specifically to dig and load material in surface mines. The electric mining shovel uses electric motors, gear reducers, drums, and
Departement of Mining, Metallurgical and Materials Engineering, Université Laval, Quebec City, Canada Abstract. Diesel-powered equipment is a backbone of modern underground metal mining. Despite its numerous advantages, emissions of exhaust gases and heat constitute a serious concern with regards to ventilation and its cost, particularly in
The selection of equipment for haulage in underground mines is a challenge due to its impact on both production rates and costs. The selected equipment should create an optimal match for the complete system and the point when equipment is to be added or replaced needs to be identified before the change is made. The use of discrete event …
Underground mining is conducted over a wide range of stope widths. The selection of equipment combinations to efficiently mine these widths is often problematic. In most …
The open stope mining method has been widely adopted in Australian underground gold mining operations due to its efficiency and productivity. This research underscores the critical importance of ...
