Rock Drilling Equipment Uses
Percussion drilling is mainly used in construction, mining and quarrying. In rock drills, the hammer creates an impact force on the drill rods or drill pipe that is transferred to the drill bit. It consists of a long rod called a drill string attached to its end. She is hit by a pole (hammer) to break stones. An advantage of the machines needed is that they are often less expensive than DTH or rotary platforms and are readily available. The downhole method (DTH) is typically used in the oil and gas industry, construction, mining (blast hole drilling) and well drilling.
The machinery used consists of a rock drill at the end of the drill string. As the drill string rotates slowly, the rock drill is continuously driven into the rock. DTH drills have many advantages over other alternatives such as rotary drills. These unique advantages include the ability to drill in almost any ground condition, ease of maintenance, minimal dust emissions, choice of hole diameters, and cleaner, more accurate holes. This drill is often the best choice for projects in cities and populated areas as it generates far less noise and vibration than other options.
The rotary technique is mainly used in underground mines and is required to drill holes of different diameters. The bit rotates downward under heavy load, breaking rock under pressure. Capable of working at any angle, the machine offers a number of benefits that make it an excellent choice for most job sites. Some of the advantages are speed, accuracy, high scores, etc. The Egyptians would have from to 3000 BC. A similar method was used.
