Applications

The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.

2. Reduced Friction The helical shape minimizes friction between the drill bit and the material. This reduction in friction leads to less wear and tear on both the drill bit and the drilling equipment, extending their lifespan.

The operation of a slurry pump involves creating a vacuum that moves the slurry from one point to another. They are typically centrifugal pumps, meaning they utilize rotating impellers to increase the fluid’s velocity, subsequently converting the kinetic energy into pressure energy. This process allows for the efficient movement of slurries over long distances, which is particularly important in large mining operations.

4. Renewable Energy Projects With the rise of offshore wind energy, submarine hammer drilling is increasingly used to install the foundations for wind turbines. The ability to achieve deep penetration in various seabed conditions makes this method invaluable in the renewable energy sector.

2. Marine Construction When constructing offshore platforms, bridges, or wind farms, the stability of foundations is paramount. Hammer drilling provides a reliable method to secure pilings and conduct deep foundation work, ensuring that structures can withstand harsh marine conditions.
