Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

Deep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Random finite element analysis on ground subsidence caused by tunnel excavation in karst regions with spatial variable soil

Deep Underground Science and Engineering, EarlyView.
This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

Deep Underground Science and Engineering, EarlyView.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

Deep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.
