Peckdrilling
Peckdrilling is a method of drilling used primarily in the mining and construction industries, particularly for creating deep holes in hard rock formations. The technique combines elements of percussion and rotary drilling to efficiently penetrate tough materials such as granite, basalt, or other dense geological strata. Unlike traditional rotary drilling, which relies solely on the rotation of a drill bit, peckdrilling incorporates a cyclic hammering action to break up rock, making it suitable for applications where high penetration rates are required in difficult conditions.
The process begins with a drill string equipped with a specialized bit, often a drag or roller
Peckdrilling is commonly used in tunneling, foundation drilling, and the extraction of deep-seated ores. Its efficiency
The technique has evolved over time, incorporating advancements in automation and materials science to improve durability
