Research report: Acoustic and mechanical responses of coal subjected to dry–wet cycling: a petrophysical perspective
New research shows that coal specimens lose up to 49.7% of their compressive strength after three dry-wet cycles, with acoustic ...
Deep Coal Mining Study Maps Floor Water-Inrush Channels
New mechanical models and physical experiments clarify how floor water-inrush channels form in deep coal mines above confined aquifers.
Roof Control Strategy Stabilizes Coal Withdrawal Channels in Close-Distance Seams
Researchers have identified overburden rotation patterns and optimal stopping-caving parameters to maintain surrounding-rock stability during equipment withdrawal in closely spaced ...
Rock Burst Mechanisms Identified in Acute-Angle Syncline Coal Mines
Researchers identified two distinct failure instability modes in coal mining faces advancing through acute-angle synclines, linking specific stress and deflection ...
Faults Can Slip Again During Gas Storage Even Without Record Pressures
Modeling of a Rotliegend-type reservoir shows that fault slip during primary production permanently redistributes stress, allowing renewed fault criticality during ...
Patterned Steel Blades Give U-Shaped Mine Supports a Rockburst-Resistant Joint
Researchers report laboratory and finite element results for a new energy-absorption joint with patterned steel blades that improves the static ...
Machine-learning model predicts when sand production begins in gas and energy wells
Researchers report a machine-learning model, trained on CFD-DEM simulations, that predicts the critical drawdown pressure gradient at which sand production ...
From Quarry Cracks to Deep Geoenergy: A Century of Rock Mechanics Revisited
A new review traces nearly a century of rock mechanics research and argues that modern geoenergy and geological storage systems ...
Research report: Post-mining flooding-induced ground displacements, microseismicity, and gas anomalies: a synthesis of research on the abandoned Ruhr, Saar, and Ibbenbüren hard coal districts in Germany
A synthesis of research on three abandoned German hard coal districts links mine flooding to microseismicity, ground uplift and subsidence, ...
