Ground Motion Estimates Updated by Building Damage

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Classical ShakeMap relies on a conditional Gaussian random field approach to earthquake shaking estimation, where the mean and covariance matrix are derived from a ground motion model, a correlation model for intra‐event residuals, and the recordings from seismic monitoring stations.

Large‐Scale Physical Model Test on the Influence of Landslide Hazards on Oil and Gas Pipeline Bending

Energy Science &Engineering, EarlyView.
This study investigates the impact of landslide geological disasters on oil and gas pipelines, focusing on pipeline deformation under varying landslide dip angles. A large physical simulation platform was used to replicate landslide effects, with experiments conducted at different dip angles to monitor stress, strain, and soil displacement. The results

Study on the Mining Pressure Law of Tunneling Roadway in Coal Pillar of Lower Coal Seam in the Mining Hollow Area

Energy Science &Engineering, EarlyView.
ABSTRACT In the downward mining, the goaf of the upper coal seam and the remaining coal pillars will have a negative impact on the stability of the lower coal seam roadway. If the roadway is excavated in the lower coal seam coal pillar, it is more likely to produce mutual superposition effects, which greatly increases the difficulty of roadway ...

Research on Grouted Steel Pipe Supports Roof Cutting and Gob‐Side Entry Retaining Support Technology for Fully‐Mechanized Caving Face

Energy Science &Engineering, EarlyView.
ABSTRACT Aiming at the roof control challenges of gob‐side entry retaining in fully mechanized top‐coal caving faces, traditional concrete‐filled steel tube (CFST) support technology exhibits limitations such as slow strength development and complex construction equipment.

Identification and Prediction Method of Working Face Water Inrush of Isolated Overburden Grout Injection

Energy Science &Engineering, EarlyView.
ABSTRACT Isolated overburden grout injection (IOGI) is an economical and efficient green mining technology. During the grout injection process, a large amount of slurry bled water will enter the underlying rock strata below the grouting layer. Under certain conditions, the slurry bled water may seep along the overlying rock layer into the water ...
