Applying Karst Hydrology Concepts to Anthropogenic Subsurface Systems and Mine Water Management

Hydrological Processes, Volume 40, Issue 3, March 2026.
Due to the pronounced similarities between natural karst systems and mine workings, we consider mine workings as man‐made karst and present the concept of ‘anthropogenic karst’. ABSTRACT Mine water management is a permanent challenge in post‐mining areas where drainage adits play a crucial role for the regulation of water levels within partially ...

Research on Directional Long Horizontal Drilling Hydraulic Fracturing Technology in Disaster Key Stratum of Working Faces

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Directional long horizontal drilling hydraulic fracturing technology (DLHDHF) can prevent and control the occurrence of rock burst disasters by controlling the hard roof in the near field. Therefore, it is exceedingly significant to enhance the pressure relief effect by determining the appropriate fracturing scheme. Taking Number 140202 working face of
