Everything You Should Know About DTH Drilling Drilling may be necessary if you have some heavy duty rocks that must be eliminated. There are numerous reasons why rocks must be drilled and excavated. Rocks are drilled and excavated for the making of specific materials or perhaps some room has to be made for a certain facility where the ground is rock-hard. There are a lot of different methods when it comes to drilling. One such method is known as DTH drilling, which is short for “down-the-hole” drilling. The name comes from the direction in which the drill carries out its task. The hammer, or percussion mechanism, follows directly after the drill bit goes down in the hole which is being created, hence “down-the-hole." There a number of different applications for this type of drilling. What is it For? DTH is not an appropriate drilling method for every type of required drilling jobs. Like other drilling methods, it is frequently used by construction workers in order to make bores for such things as heat pumps, to drill wells for water, or even make large piles of rock that might be needed for other projects. It is commonly used for mining, and can even be used to create blast holes, where explosives are left in order to lift rock to get to deeper ore. This sort of drilling could easily be used for all sorts of different construction purposes because of its different applications; these include mining, blasting and gas and oil access. What Tools Are Needed? The hammer and drill bit are the main parts that are used in this type of drilling. The hammer is known as a percussion mechanism. The hammer is in fact what helps to guide the bit into the rock. To transfer energy into the rock, the machines uses drill pipes against the hammer, compressed air and the drill bit. With this ingenious design, the impact energy actually does not go through any joints. This creates less risk of something breaking apart, which is perfect for helping smaller digging rigs get results just like larger ones. Sizes and Types Hammers and bits can be found in many different sizes in order to create holes that range from small to large. Depending on the type of bit, some may be more resistant to breaking than others. You should consider the size of the hole which needs to be drilled as well as the type of rock that you are drilling through when picking your bit. An abrasive type of rock would most likely require the use of a different bit than a smoother rock would require. As mentioned, DTH drilling, or “down-the-hole” drilling gets its name mostly from the fact that the hammer guiding the drill bit follows the bit down the hole. From blasting rock to constructing water wells, it has a wide variety of useful applications. Like other forms of drilling, the equipment can be used to make drill holes of varying sizes. Since investing in hammers and bits is no small matter, it's important to understand the amount of force that you need, the size of hole you would like to drill, and even the type of rock that you will be drilling through before purchasing equipment. Different types of bits will probably be required for different types of rock. If your project could benefit from this kind of drilling, make sure you get quality equipment and help to get the job done Rock Hog
