Practices on rockburst prevention and control in headrace tunnels of Jinping II hydropower station

Journal of Rock Mechanics and Geotechnical Engineering, 2012
AbstractRockburst problems induced by high in-situ stresses were prominent during construction of the headrace tunnels of Jinping II hydropower station. The rockbursts occurred in various forms, and it is necessary to take pertinent measures for integrated prevention and control of rockbursts.

Study on the rockburst risk of alternate exterior entry under island coal pillar

Energy Exploration & Exploitation
The extraction of extremely thick coal seams through slicing mining requires leaving behind several island coal pillars in the top slicing, which could lead to rockburst in the bottom slicing.

Research on the prevention and manage of rockburst in deep‐seam mining roadways

Energy Science & Engineering
AbstractThis study presents a strategy for preventing and controlling rockbursts in deep and vast seams during the mining operation. We analyzed the main factors influencing rockburst by combining the geological structure of the rock mass with field‐collected microseismic monitoring data.

Temperature effect of rockburst in granite caverns: insights from reduced-scale model true-triaxial test

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
To investigate the influence of thermal treatment on the rockburst in granite caverns, true-triaxial compression tests were conducted on pre-heated granite cubic samples containing a circular through-hole using a true-triaxial test system, and the micro ...
