A collar usually contains a maximum of three 'steps'. The first lining step typically ranges between 1 to m in width, but can be as high as 2m. It is recommended that the first step occur below the limit of frost penetration. ... For the bucket to be stable during the sinking process the width to height ratio should be 2:1.

Δpl = f ⋅ 1 2ρ v¯2 ⋅ L d pressure loss in a straight pipe section (3) (3) Δ p l = f ⋅ 1 2 ρ v ¯ 2 ⋅ L d pressure loss in a straight pipe section. The friction factor can also be calculated mathematically based on the geometry of the pipe, as will be shown later. Note that this formula only applies to straight pipe sections.

Air velocity of coal mine ventilation is an important consideration that may cause serious damage. This paper proposes a simple, low cost and effective air velocity monitor (AVM) for coal mine ventilation. The AVM uses the lockin characteristic of vortexinduced vibration (VIV) to sense the air velocity.

20. Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% ...

The Venturi effect can also be proven by studying Bernoulli's equation, which is: ( v 2 /2 ) + gh + ( P/ρ ) = Constant. Here, v is the flow velocity. g is the gravitational constant. h is the elevation, in the direction opposite to gravity. P is the pressure at any point in the fluid. ρ is the mass density.
