Current status and future trends of deep mining safety mechanism and disaster prevention and control

Abstract

In recent years, there have been a number of developments in deep mining research with respect to safety mechanisms and disaster prevention and control. However, it will be difficult to fully resolve the challenges associated with disaster prevention and reduction based on current theories and technologies, and as yet no sound deep mining research approach regarding cataclysm and its control has been established. This paper reviews the literature and discusses problematic research areas associated with deep mining disasters, including in-situ stress measurement and its distribution law, deep rock mechanics and the coupling damage mechanism, dynamic disaster mechanism and prediction, and the water inrush mechanism and early warning, as well as the surrounding rock deformation mechanism and control technologies. This paper analyzes the deficiencies in existing research and identifies key problems that must be solved in deep-mining-induced disasters. Lastly, this paper indicates future prospects in the study of ultra-deep mining disasters.
