The angle at which the surface of a cutting edge in a drill bit is inclined in relation to the surface of the material being cut.
Industry:Mining
The angle at which the wall of an open pit or cut stands as measured along an imaginary plane extended along the crests of the berms or from the slope crest to its toe.
Industry:Mining
The angle between the abscissa and the tangent of the curve representing the relationship of shearing resistance to normal stress acting between soil and the surface of another material.
Industry:Mining
The angle between the direction of the resultant stress or force acting on a given plane and the normal to that plane.
Industry:Mining
The angle between the horizontal and the surface slope of any pile of material formed by free fall of the material.
Industry:Mining
The angle between the perpendicular to a surface and the resultant force acting on a body resting on the surface, at which the body begins to slide.
Industry:Mining
The angle between the planes of maximum shear, which is bisected by the axis of greatest compression.
Industry:Mining
The angle between the vertical and an inclined plane bounding the area affected by the subsidence beyond the vertical. Applied to slides of earth.
Industry:Mining
