Web11 Apr 2024 · The caving height ratio decreases with an increase in the mined thickness and the correlation can be described by a power function. The maximum allowable height of the caving zone and mined thickness are determined based on the thickness of the bedrockand the changed tendency of the caving height ratio. The various terms related to airfoils are defined below: • The suction surface (a.k.a. upper surface) is generally associated with higher velocity and lower static pressure. • The pressure surface (a.k.a. lower surface) has a comparatively higher static pressure than the suction surface. The pressure gradient between these two surfaces contributes to the lift force gen…
