Abstract Mine flooding accidents have occurred frequently in recent years, and the predicting of mine water inflow is one of the most crucial flood warning indicators. Further, the mine water inflow is characterized by non-linearity and instability,

Abstract Disasters caused by mine water inflows significantly threaten the safety of coal mining operations. Deep mining complicates the acquisition of hydrogeological parameters, the mechanics of water inrush, and the prediction of sudden changes in

Abstract Mine water inflow is an important basis for the formulation of mining plans and the utilization of groundwater resources. The mine water inflow is the result of the combined influence of many factors. The weight value of the influencing fact

In the process of coal mining, accidents such as water inrush in mines can not only cause huge economic losses, but also seriously threaten the safety of workers. Hydrogeological parameters play an important role in calculating the amount of water in

The distribution of overlying rock fractures and water inflow during mining in shallow and thick coal seams under the river is one of the decisive factors for the safe production of working faces. Numerical simulation is an important prediction metho

Low crop diversification in highly productive areas has led to declines in total organic carbon (TOC) in soil, essential nutrients for plant’s growth and microbial diversity/activity. This could have an impact on the movement of water in the soil p

Tunneling operations face a significant challenge in managing water inflow into excavated underground spaces, primarily initial or excavating caused discontinuities in tunnel walls. The water flow rate is intricately linked to the geometric shape of
