Other Types of Shovels. For cleaning up snow and other debris, 15-1/4 x 19-3/4 inch shovels will be sufficient. There are also some shovels that measure 13-1/2" x 14-1/2". Other shovel variants you will come across are those measuring 13-1/2" x 14-1/2" and 14-1/2" x 15-1/4". Aside from the size difference, there are also many types available.

[PDF]There are three different mechanisms of discrete, continuous, and hybrid material transportation in open mines, including (but not limited to) (i) truck and shovel system (discrete), (ii) slurry piping (continuous), and (iii) in-pit crusher and conveyor belts (hybrid). Although each mechanism has its own advantages, the truck and shovel system
