  • What is Blasthole Drilling? - Definition from Petropedia

    Blasthole Drilling is a drilling technique whereby a hole is drilled in the rock surface up to certain depth, and then explosives are loaded to induce cracks on the hard surface of the inner geology formation for further deep drilling. This hole which is meant for loading explosives is known as a blasthole. Blasthole Drilling is one of the techniques of surface drilling.
