Taper drill rod, Integral Drill Rod
The Most Common Rock Drilling Methods You Should Know Drilling and blasting both have a significant part during mining production. If we talk about the most common or widely used methods of rock drilling, there are three names that come on the top
Rotary drilling DTH- Down the Hole drilling Top hammer drilling
All of these methods re considered for all types of mining operations. It is very important for someone to have ample amount of knowledge about the tool; using the equipment wrongly or wrong choice can cause huge loss. In this article, we would cover important info about introduction and working principles. Take a look: Rotary Drilling: In this kind of drilling, the rig is responsible for supplying enough shaft pressure and rotary torque. The bit in the drill keeps drilling and rotating on the rock, which leads to static and dynamic impact pressure on the rock. Constant rotation and grinding make the rock to the fracture. Compressed air and flow rate from the nozzle make the slag continuously blown from the hole while keeping the annual space between the dill pipe and the wall. The method is adopted for soft and medium soft rock drilling. Down-The-Hole Drilling: The process of DTH is carried out to drive the hammer via the drill pipe. The piston strikes the drill bit directly. On the other hand, hammer external cylinder remains straight and stable. As a result, the arrangement does not loss the energy in the joints and also allow deeper percussion drilling. The impact force in DTH drilling remains more efficient and straighter other types of drilling operations. The method is ideal for hard rock drilling and rock formation conditions. Top Hammer Drilling: The percussive force produced by the piston in the hydraulic drill rig is sent to the drill bit through the medium of shank adaptor and drill pipe. The percussion system creates drilling system rotation. The time stress wave reaches the drill bit, bit penetration happens causing drilling holes into the hard rock. Air compressor removes dust and slags. Top hammer drilling through tapered drill rod is used for the hole diameter of maximum 127mm and depth less than 20M. This method is adapted to stable and uniform hard rock. It gives high efficiency in shallow hole drilling. From Where You Should Buy Drill Rods? Drill rods has a significant role in each type of drilling. Therefore, you should always select a reliable, experienced, prominent, and best mining equipment manufacturing company like DRILLMAN. These companies are famous for delivering high-quality equipment and also for their strong online presence in the market. Whether you want taper drill rod or integral drill rod for your mining needs, do not forget to keep this consideration in mind.
