Analysis of mine water inrush accident based on FTA
Procedia Environmental Sciences, 2011 AbstractFlood hazard is one of the common disaster accidents in coal production. And it not only brings huge property loss, but also threatens life safety all the time. It is of great significance to identify the source of water inrush in the process of coal production. This paper applies FAT to analyze the hazard common source of mine water inrush.

On the theory of compliant wall drag reduction in turbulent boundary layers [PDF]
A theoretical model has been developed which can explain how the motion of a compliant wall reduces turbulent skin friction drag. Available experimental evidence at low speeds has been used to infer that a compliant surface selectively removes energy ...

Water Inrush Mechanism During Mining Adjacent to Large Water-Conducting Faults
WaterIn mining operations, the rock mass located between the water-conducting fault fracture zone and the waterproof protective coal column is highly susceptible to damage, which may result in sudden water inrush disasters. This paper first employs indoor experiments and on-site rock sample analysis to determine the macroscopic mechanical parameters of ...
