Deep Underground Science and Engineering, EarlyView.This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Energy Exploration & Exploitation, 2018 The coal measure strata formed in the late Paleozoic era underwent tectonic movements on several occasions, leading to the development of a range of fold structures in the strata as a result of highly interlayered gliding and shearing deformation.

Deep Underground Science and Engineering, EarlyView.In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.

Deep Underground Science and Engineering, EarlyView.The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

Crustal deformation in extensional regimes: Iceland, Nevada and SW Turkey [PDF]
, 1996 In 1991 a 23-point, 30 x 25 km, GPS geodetic network was established in the Hengill ridge-ridge-transform triple junction, SW Iceland. The GPS data were processed using the Bernese V3.2 software.

Dynamic cracking properties and generating conditions of coal under rapid gas release
Deep Underground Science and Engineering, EarlyView.Gas release tests revealed that crack initiation and propagation are jointly controlled by initial crack length, residual strength, and gas release velocity. A new outburst risk coefficient was thus developed from a fracture mechanics perspective, offering a novel predictive approach.

Neogene paleomagnetism and geodynamics of the Hikurangi margin, East Coast, New Zealand [PDF]
, 2006 Vertical-axis rotations are an important component of Neogene deformation in the New Zealand plate boundary region, and potentially offer fundamental insights into the rheology of continental crust.
