Experimental Study on Flow Characteristics of Aeolian Sand in Fractures
Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 It is one of the important safety problems in the process of mining shallow coal seams in western China that the rock mass affected by mining stress breaks and forms a penetrating fracture, leading to a sand burst in the working face. The self‐developed test system is used to carry out the experimental study on the flow characteristics of Aeolian sand ...

Geofluids, Volume 2026, Issue 1, 2026.Water inrush poses a serious threat to the safety and sustainability of coal mining operations, particularly in arid–semiarid regions where confined aquifers overlie coal seams. Therefore, an accurate assessment of roof water inrush risk is essential to prevent water hazards on the roof.
