Summary editorial for karst hydrogeology: advances in karst collapse studies

Environmental Earth Sciences, 2018
Karst collapses occur in various sizes and by various mechanisms. No karst collapses are the same, and each needs to be treated individually. Decades of investigation of and experience with these collapses make it clear that addressing karst collapse hazards requires a multi-disciplinary approach that integrates geomorphology, engineering geology ...

Seepage property of karst collapse pillar: experiments and engineering applications

Arabian Journal of Geosciences, 2021
The Karst collapse pillar (KCP) is a special geological structure, which is easy to form the fissure channels between the coal seam working face and the aquifer to cause the water inrush disasters. The KCP was sampled on site in this paper. The confined uniaxial compression test was carried out on the KCP to simulate its field consolidation, and ...

Characteristics and evolution of karst collapse columns in the Huainan coalfield

Science of The Total Environment, 2023
Karst collapse columns (KCCs) seriously affect the mining safety of deep coal seams. This study systematically summarizes and analyzes the development of KCCs, and classifies the different development stage to identify their development stages and evolutionary process in the Huainan coalfield.
