Dr Abouzar Vakili
Principal Geotechnical Engineer
Mining One
Does a factor of safety of 1.2 mean anything? The hidden drivers of factor-of-safety variability in open pit slopes
11:10 AM - 11:25 AMBiography
With over 20 years in the mining industry, I specialize in geotechnical engineering and numerical analysis to support geotechnical design and mine planning. At Mining One Consultants, I lead advanced geomechanics analyses, collaborating on challenging projects involving deep and high-stress underground and open-pit mines. My work focuses on delivering rigorous, data-driven solutions to enhance operational safety and better mining productivity.
As the founder of Cavroc, I have developed a platform that democratizes access to cutting-edge geotechnical numerical modeling tools, enabling engineers to tackle complex challenges with user-friendly solutions. My mission is to advance the geotechnical engineering field by integrating innovation and practical application.
Dr Dina Kon
Researcher
China University of Mining and Technology
Slope stability analysis using Fellenius method with a Fractal-Enhanced Mohr–Coulomb (FEMC) model
11:25 AM - 11:40 AMBiography
Dina Kon Mushid is a researcher in Mining Engineering at the China University of Mining and Technology (CUMT), specializing in rock mechanics, slope stability, and geotechnical risk mitigation within open-pit mining contexts. She possesses a Master’s degree in Civil Engineering from Shanghai Jiao Tong University and a Bac+2 degree in Exploration and Mining Geology from the University of Kolwezi, DR Congo. At AAC Mining Executors Group, she significantly contributed to enhancing site safety and operational efficiency by conducting comprehensive geotechnical field assessments, designing customized ground support systems, and implementing real-time monitoring protocols, which markedly reduced slope failure incidents. Her field experience in major operations, such as the Kamoto Copper Company, has further solidified her expertise in practical geomechanics. Her research investigates the application of fracture mechanics to complex rock failure patterns, particularly in the copper-cobalt deposits of the DRC. Her findings have been disseminated in several peer-reviewed journals. Proficient in French and English, with a working knowledge of Chinese, she continues to bridge industry practice and academic innovation in mining geotechnics.
