Abstract

Mining for resources (minerals and non-mineral materials) are in constant demands as the world economy is growing. Open-pit mining is the most widely used technique today as compared with the underground mining. In any of these two mining methods, they all start with drilling and blasting.

Three rock drilling methods, top hammer, down-the-hole, and rotary are presented. Techniques for drilling the right size of hole at the optimum efficiency are discussed.

Applications of utilizing these methods are presented.
