Blaster's Training Modules Module 4 Blasthole

Blasthole Drilling 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 the changes in geology

situations may also require the adoption of a higher velocity, more energetic explosive. Where drilling and blasting conditions are both severe, the operator should use premium explosives, at least in the bottom one third of the drill hole. Clearing the toe, and therefore contributing to a smoother floor, is a major asset to improve BLAST DESIGN

An integrated approach to the drill and blast process

Aug 12, 2020 Like many catchy mining phrases, “Drill to Mill,” “Pit to Plant,” “Mine to Mill” and “Mine to Market” are deceptively simple descriptions for complex, multi-layered processes. In the mining cycle, drill and blast (D&B) is arguably the first and most important step to get right. D&B operations impact the entire mining process
