Ground vibration isolation using mass scatters: A comparative study with trench barriers and wave‐impeding blocks

Deep Underground Science and Engineering, EarlyView.
Ground‐borne vibrations are a frequent source of environmental problems. A full‐scale experiment is conducted to validate a 3D numerical model in order to analyze the efficiency of three methods of isolation. Trench barriers and wave‐impeding blocks are impractical and expensive methods of isolation, but mass scatters appear to be an efficient ...

The effect of thermal–hydro–mechanical coupling on grouting in a single fracture under coal mine flowing water conditions

Deep Underground Science and Engineering, EarlyView.
Higher temperature leads to a better relative sealing efficiency with a slow flow rate. Temperature change shows a negative correlation with the seepage pressure and the grouting pressure. The “equivalent grouting point offset” effect of grouting shows an eccentric elliptical propagation.

Elevated temperature effects on swelling pressure of compacted bentonite

Deep Underground Science and Engineering, EarlyView.
We present a set of new experimental investigations on the effects of elevated temperature on the swelling pressure development of compacted bentonite. This research was motivated by an emerging interest in using bentonite as a plug material in oil and gas well abandonment.
