DTH is an abbreviation for "down-the-hole. ” That means that the drilling takes place deep within the hole being drilled. In standard drilling, a round drill is utilized to penetrate the rock. In DTH hammer drilling, a hammer is hammered instead of an ordinary drill through a variety of soil/rock formations. Tied to the drill bit, this air pressure-driven hammer does the work. Once the hammer finally strikes the rock at the bottom of the hole, small cracks appear and pieces of rock are chiseled away. Air or water is then used to push the pieces out of the hole, keeping it clean for more drilling.
DTH hammer drilling is a good authorized one to show advantages for multi-functions. And perhaps, its most important benefit is its speed. They are capable of drilling holes significantly faster than traditional means of drilling. Faster drilling means faster project completion. The hammer can penetrate the solid rock far more effectively than a drill bit would be able to, so drilling takes less time. Spending less time drilling can free up time to do other valuable work, this can reduce costs and deliver more successful outcomes.
Significant Advantages of DTH Hammer Drilling Another major advantage of DTH hammer drilling is its accuracy. The hammer smashes small cracks into the rock, working to govern how the hole is drilled. This is particularly vital when bore holes are deep because it minimizes the risk of the drill falling out of track. This is important for making sure that the hole goes to precisely the right place. The more accurate the drill, the less rock has to be blasted out of the hole, which in turn can preserve costs as well.
Pushing compressed air down the top of the drill string causes the piston inside the hammer to move back and forth. For each downward stroke of the piston, it hits the drill bit. That impact works a force sharply down onto the bedrock at the bottom of the hole. The drill bit strikes the rock, generating tiny cracks that break the rock. Compressed air blows those tiny rock pieces out of the hole to keep everything clean and clear for more drilling.
DTH hammer drilling vs Other Drilling Methods So, how does DTH hammer drilling compare with other drilling methods? One advantage is its ability to penetrate through hard rock with greater efficiency than that of the rotary drilling system. That is because the hammer can push down much harder, making it easier for it to break up the rock. DTH hammer drilling is also more precise than rotary drilling. Doing this allows for better control in the directional and angle of the hole, which is critical for many drilling projects.
There is another significant difference with regards to the volume of holes that can be drilled. GTK | Geological Survey of Finland DTH hammer drilling can produce larger holes than with traditional rotary drilling methods. The hammer creates a larger cavity inside the rock which there afterwards can be drilled out from the block to a bigger hole. This characteristic makes it the best way for drilling various kinds of wells like; water wells, oil & gas wells, geothermal wells, etc.
A wide variety of DTH hammer drill has been developed by Kaiqiu, which can greatly improve drilling operation. The first reason is the quality and durability of hammers, which are made of high-quality materials, enabling them to withstand mostlyaperformance of their job. Expanded Fit It Comes in a different size from small hammers for shallow drilling to larger hammers for deep drilling projects.
