COAL MINING INDUSTRY INFORMATION - ASGCO

Room-and-pillar mining. In room-and-pillar mining, coal deposits are mined by cutting a network of 'rooms' into the coal seam and leaving behind 'pillars' of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam – although this coal can sometimes be recovered at a later stage. Longwall mining. Longwall mining involves the full extraction ...

Selecting the Optimal Conveyor Drive

Designer should select an appropriate VFD for the 15 HP belt drive motor. However, note that since the VFD must be located more than 30 feet from the drive motor, the designer should also specify an output filter on the VFD. The reason is that resonant frequencies can occur on the line between the VFD and the motor causing a voltage spike and damaged motor. Case Two: The manufacturer of this ...

CONVEYOR PULLEY SELECTION GUIDE - pcimfg · PDF file

The amount of traction between a drive pulley and a belt can be increased by increasing the arc of contact between the two surfaces. The arc of contact, or belt wrap is the angular distance a pulley travels while in contact with the belt, and is measured in degrees. Increasing the area of contact between two surfaces does not increase the coefficient of friction between the two surfaces. As ...
