by KeAi Communications Co. Mining of minerals is important for the advancement of modern society. However, over many years of mining, shallow resources are depleting with the need to migrate to deep levels.
Mining at depth presents notable challenges, and among the foremost concerns is the occurrence of rockbursts, which are characterized by sudden and violent releases of accumulated strain energy within the rock mass. Consequently, this pose significant threats to the safety of personnel and the integrity of underground infrastructure. In a study in the journal , Dr.
Ming Cai from Laurentian University in Canada presents a new approach on rockburst risk management. "The research emphasizes the critical importance of understanding rockburst risks and explores the factors influencing these occurrences, risk assessment methodologies, and various control and mitigation techniques," shares sole author Cai. "As rockburst risks stem from a combination of the rockburst hazard, excavation vulnerability and exposure, risk control needs to be focused on these three aspects.
" The paper advocates for strategic measures to reduce rockburst hazards and excavation vulnerability, with a particular emphasis on the importance of ground support systems. Additionally, it explores rockburst warning and prediction, addressing the challenges and highlighting the significance of advanced monitoring techniques and engineering control measures. "Even if we can predict rockbursts, so what? Assuming tha.
