About How to discharge powder from rock drill
As the hole is drilled, the bit grinds the rock into a fine powder. This powder, or rock “cuttings”, are then flushed out of the borehole by a high-pressure air system run by the large compressor mounted on the drill rig.

This module presents aspects of surface drilling that are important to blasting operations. The purpose of drilling into rock is to provide a “blasthole” into which explosives can be loaded. Good drilling practices include carefully monitoring drill-rig operating parameters, taking careful notes of.
Effective blast design rules of thumb involve key principles such as safe distance to structures, optimal powder factor, accurate hole depth calculations, and adherence to established rules to ensure controlled and efficient blasting operations. HOLE DIAMETER (d) = hole depth (H) divided by 5 to.
