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.

DTH drilling refers to a method where the drilling bit is located at the end of a drill string, below the surface of the ground. This technique is distinguished by the use of high-performance percussion hammers, which are positioned on the drill bit. DTH drilling involves the use of compressed air to deliver rapid impacts, breaking rock into smaller fragments. This method is particularly effective in hard rock formations, making it a preferred choice for mining operations and various drilling applications.

Trotz der Fortschritte in der Technologie stehen Hersteller von Sandpumpen vor mehreren Herausforderungen. Eine der größten Herausforderungen ist der globale Wettbewerb. Besonders in aufstrebenden Märkten steigen die Anforderungen an Preis und Qualität, was es etablierten Unternehmen schwer macht, ihre Marktanteile zu halten. Darüber hinaus müssen die Hersteller sich ständig an sich ändernde Umweltvorschriften und Marktbedürfnisse anpassen.

The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal.
