A Risk Assessment Method for Rockburst Based on Geodynamic Environment

, 2018
Rockbursts are the sudden release of accumulated energy in surrounding rock of roadway and stope. Current studies on the rockburst mechanism are primarily focused on underground mining space and mining activities, whereas efforts have rarely been focused

Research on Stress Characteristics of Rockburst in Over-Length Deep-Buried Tunnel

Buildings
As a unique geological hazard in a high-geo-stress environment, rockburst happens with strong suddenness, randomness, and destructiveness, but the mechanism of its occurrence in a deep-buried tunnel in a high-geo-stress environment needs further study ...

The failure behavior of coal-rock combined body under compression-shear loading

Science Progress
As shallow coal reserves continue to deplete rapidly, deep mining has become an unavoidable course of action. In the process of deep coal mining, affected by blasting, mining, and excavation, the coal-rock interface often encounters the action of ...
