Submarine hammer drilling, often referred to as underwater percussion drilling, is an advanced technique utilized primarily in marine construction and resource exploration. This method combines the principles of traditional drilling with hydraulic and pneumatic operations, enabling the effective penetration of hard substrates beneath the sea floor. In this article, we will explore the processes, equipment, advantages, and applications of submarine hammer drilling.
1. Rotary Drills These are commonly used for deep hole drilling, making them ideal for mineral exploration. Rotary drills operate using a rotating drill bit that cuts through rock layers with the aid of a drilling fluid that cools the bit and removes cuttings from the hole.
