The ore pass is a vertical or steeply inclined opening through which rock flows by gravity from upper to lower levels. Ore passes are sometimes arranged in a vertical sequence to collect ore from upper levels to a common delivery point on the haulage level. The chute is the gate located at the bottom of the ore pass. Ore passes normally end in ...

Before explosives in the form of gunpowder were introduced to mining in the 1600s, miners carved rudimentary small-scale stopes by hand.. Gunpowder was replaced by dynamite in the mid-1900s, and power tools and machinery followed shortly after. As technology progressed, so did the mine design process.
