Yizhuo Li

Yizhuo Li is a lecturer at the University of Science and Technology Beijing. She obtained her Ph.D. in mining engineering and received three years of excellent doctoral awards from McGill University. Dr. Li has conducted innovative research in rock mechanics for estimating mining-induced stress and analyzing front stability in underground mining, employing laboratory experiments, field tests, analytical model development, and numerical modeling. Her research makes significant contributions to the design, planning, operations, and ground control safety of hard rock mines.

Dr. Li has developed a novel technique called the Diametrical Core Deformation Technique (DCDT) for near-field stress orientation and magnitude estimation in underground mining. She has established a systematic methodology based on rock core diametrical deformation, which can be applied in any hard rock mine without the need for sophisticated measuring equipment in the field. This technique provides a practical and cost-effective solution for estimating mining-induced stresses and their orientation. Dr. Li has also proposed a new methodology for assessing mining face stability, which involves DCDT in combination with 3D numerical modeling. This study indicates that DCDT can be a practical tool for the assessment of mining face stability.
