Water inrush is one of the most dangerous disasters in coal mining. Due to the large-scale
mining and complicated hydrogeological conditions, thousands of deaths and huge …

China's coal mines face very complicated hydrogeological conditions and are affected by
many complex water hazards. Based on the condition of the coal seams and an analysis of …

When fault fracture zones are encountered in the mining tunnel excavation, the water-
conducting pathway is easily formed by the granular structure of the broken surrounding …

In this paper, the hydrogeological characteristics in the southern coalfields of China are first
briefly outlined. Then, taking the Meitanba mine as an example, the evolution and modeling …

This study assessed the geochemistry and quality of groundwater in the Hongdunzi coal
mining area in northwest China and investigated the mechanisms governing its …

Extraordinarily severe coal mine accidents (ESCMAs) are characteristized by thirty fatalities
or more in one accident. In this paper, such ESCMAs are analyzed using 188 cases which …

The evaluation of the hydraulic properties evolution of granular sandstones in relation with
groundwater inrush within faults is an important issue for mining engineering applications …

In the process of green and smart mine construction under the context of carbon neutrality,
China's coal safety situation has been continuously improved in recent years. In order to …

Coal mining-induced groundwater losses may trigger water inrush disasters and surface
ecological degradation. The compaction and seepage characteristics of broken rock in gobs …

The instability and failure of water-bearing coal mass can lead to serious coal–rock dynamic
disasters, such as mine water inrush. It brings severe challenges to the safety produce …
