Stemming blast hole collar in surface mines with an inert material redirects blasting energy to the rock more efficiently so, the energy is utilized more effectively in breaking rock. Cevizci [1] studied the effect of plaster stemming in quarry blasting and found plaster stemming was very efficient in plugging the blast holes.

Quarry resources refer to any common rock or other mineral substances as the Director of Mines and Geosciences Bureau may declare to be quarry resources such as granite, limestone, and marble among others. A person may be allowed to extract and utilize quarry resources on public or private lands through the issuance of a quarry permit.

The quarry becomes deeper with each subsequent bench, with stepped benches reaching up to the original surface. With few exceptions, modern quarries rely on drilling and blasting to fragment the rock, which is then loaded onto offhighway trucks or belt conveyors for transport to a processing plant of some sort.
