Deep Underground Science and Engineering, EarlyView.Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

ABOUT USING THE GEOPHYSICAL STUDY METHODS TO PREVENT DRILLING PROBLEMS
Известия высших учебных заведений: Нефть и газ, 2016 The methods of geophysical survey used for prevention of complications in terms of stability of well borehole when drilling are considered. It is shown that application of the borehole survey complex, including section gage logging, borehole acoustic TV (

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.

Deep Underground Science and Engineering, EarlyView.This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Characterization of Shale-Drilling Fluid Interaction Mechanisms Related to Wellbore Instability
Journal of King Saud University: Engineering Sciences, 1996 Wellbore stability problems tend to occur during the drilling phase in shale sections, hence the understanding of shale-drilling fluid interaction mechanisms is essential if wellbore instability is to be avoided when drilling through shale sections.
