Deep Underground Science and Engineering, Volume 5, Issue 1, Page 127-143, March 2026.In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio

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 ...

Recognition of rock–coal interface in top coal caving through tail beam vibrations by using stacked sparse autoencoders [PDF]
, 2016 This paper provides a novel rock-coal interface recognition method based on stacked sparse autoencoders (SSAE). Given their different size and hardness, coal and rock generate different tail beam vibrations. Therefore, the rock-coal interface in top coal
