Core drilling, which drills in the rock in a rotating manner, should be noted that the core drilling operation gives the miner the most practical and reliable information about the depth of the area.
Rotary drilling or coring uses a sharp rotating drill bit to drill into the earth’s crust. Much like hand drilling, the rotation of the drill bit makes it possible to penetrate the hardest rocks. The idea of using rotary drilling is not new. While the concept of rotary drilling—using a rotary auger to drill into rock—seems simple, the actual mechanics of the new equipment are quite complex. In addition, technology is rapidly advancing and new innovations are constantly entering the field. The rotary drilling system basically includes four groups of components. The prime mover, suspension system, rotation system and fluid circulation system together make core drilling possible.
