Failure mechanism of the coal wall at the working face based on an eccentric compression mechanical model

Deep Underground Science and Engineering, EarlyView.
In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio

Application of Freezing Method in the Geology Disaster Treatment of Fault Fracture Zone

DEStech Transactions on Engineering and Technology Research, 2017
Fault rupture zone inrush of water and mud is the most serious geological disaster of the tunnel and underground engineering. The disaster has a direct threat to the progress of engineering and the safety of builders. The Yonglian tunnel appears to multiple inrush of water and mud disaster in the process of construction Geological environment and ...

Experimental study on dynamic behavior analysis of coal and its acoustic emission response characteristics under impact failure

Deep Underground Science and Engineering, EarlyView.
Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring
