The Psychological Wellbeing Of Women Operating Mining Machinery In A Fly-In Fly-Out Capacity, Anne Bailey-Kruger
The Psychological Wellbeing Of Women Operating Mining Machinery In A Fly-In Fly-Out Capacity, Anne Bailey-Kruger
Theses: Doctorates and Masters
The present study aimed to address the gap in the current mining research by investigating women’s experiences of working in the mining industry in a “bluecollar” work role and the impact of fly-in fly-out (FIFO) mining on their wellbeing. An Interpretative Phenomenological Approach (IPA) was used as a framework to explore the experiences of 19 female machine operators through in-depth interviewing at one mineral mine site in Queensland, Australia. IPA analysis revealed three themes as identified by the participants. The first theme described how workplace barriers to job progression were salient issues for the women, particularly in respect to discrimination …
Geostatistical Methods For Estimating Iron, Silica And Alumina Grades Within The Hardcap Of The Section Seven Iron Deposit, Tom Price, Philip John Savory
Geostatistical Methods For Estimating Iron, Silica And Alumina Grades Within The Hardcap Of The Section Seven Iron Deposit, Tom Price, Philip John Savory
Theses: Doctorates and Masters
Many iron ore deposits have a weathered zone (Hardcap) near the surface which is highly variable in grades. Estimating the amount of ore grade material (HG) in this zone is difficult as a result of this variability. The Section Seven Deposit at Tom Price is largely mined out and has production data available in the form of grade blocks that were marked out during mining as HG and non- HG. Hardcap domains and a block model representing them were created and estimates were made from original exploration data using Ordinary Kriging, Global Change of Support, Indicator Kriging and Median Indicator …
The Simulation Of Material Types In A Western Australian Iron Deposit, Jacqueline Ferreira
The Simulation Of Material Types In A Western Australian Iron Deposit, Jacqueline Ferreira
Theses: Doctorates and Masters
Geostatistical methods are currently used by mining companies to determine a resource model of the tonnage and head grade that may be obtained from a potential orebody, making it one of the first and most vital operational stages in any mining project. Currently long term mine planning is based on the estimated head grades model, which provides vital information on the quality of the ore. The risks associated with mining a particular ore may be reduced if geometallurgical information, such as material types, is incorporated into the operational flow model. Material type proportions are obtained from evaluated reverse circulation (RC) …
