METHODS/TYPES OF DRILLING Drilling is a cutting process that uses a drilling rig machine to cut a hole of circular cross-section in solid materials like land or mud. This rig includes the drill bit which is usually a rotary cutting tool, often multi-pointed.

DTH Driling Rigs Drill Bit Damage Analysis (Part 2) DTH drilling rigs are mainly based on high-frequency impact crushing methods, which can often achieve more than 10 times the drilling speed of conventional drilling methods.

Introduction For Down-The-Hole Drilling Method A down-the-hole drill, usually called DTH, is basically a mini jackhammer screwed on the bottom of a drill string.

De-dusting System and Principle of DTH Drilling Rigs During the operation of a DTH drilling rig, not only is the dust concentration at the workplace high but also the dust particles are widely distributed.
