Mitigation of Underground Engineering Disaster

Abstract

Meantime, because of engineering disturbance and complex geological conditions, engineering geological disasters such as large deformation, rock burst, water inrush, and surface subsidence occur frequently in the process of underground engineering and construction, causing casualties, equipment damage, project delay, engineering failure, etc. [...]the disaster prevention and construction safety of underground engineering has become the focus of worldwide experts in the field of civil engineering. The paper “Analysis of the Thermal Characteristics of Surrounding Rock in Deep Underground Space” authored by L. Chen, J. Li, F. Han, Y. Zhang, L. Liu, and B. Zhang studied the effects of heat transfer time, airflow velocities, and air temperature and radial displacement on the distribution characteristics of temperature. In view of the phenomena of coal and gas outburst induced by fault activation under dynamic disturbance, a mechanical model of faults and surrounding rock mechanics was established based on the theory of fold catastrophe in the paper “Study on Catastrophe Theory of Activation-Induced Prominence of Faults under Dynamic Disturbance.”
