Frequently Asked Questions
What is DTH Hammer?
Down-the-hole drilling (DTH) involves a drilling hammer positioned at the bottom of a drill string. The system operates using three essential elements for efficient hole drilling: bit loading (weight), rotation, and air pressure. These components work together to effectively crush rock formations.
What are mining drill bits made of?
Located at the tip of the drillstring, drill bits typically consist of two or three cones constructed from extremely hard materials such as steel, tungsten carbide, and/or synthetic or natural diamonds. The sharp teeth on these cones are designed to cut through rock efficiently.
How does DTH system work?
Down-the-hole drilling systems utilize compressed air to power a hammer mechanism that delivers high-impact blows directly to the drill bit. This method provides efficient rock breaking capability while the rotation ensures proper hole formation.
