Drilling Equipment - The old timers used cable tools to drill wells, which meant repeatedly dropping a heavy drill bit on the end of a hemp rope - the cable - down a well hole to slowly deepen it. When the cable was pulled from the hole, they wound it around a spool with " bull wheels " on either side, as shown in the photo on the left taken ...

The percussion drilling itself is classified as top-hammer drilling (THD), down-the-hole (DTH) drilling, and rotary drilling (RD) rigs, depending on the operating method used (Song et al., 2016).Fig. 2.7 shows various methods. In general, THD is used mostly for mining and civil blasting works, for which the drilled hole is restricted to a length of 40 m at the most.

A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud ). The DTH hammer is one of the fastest ways to drill hard rock.

High inside sample circulation is achieved by having the appropriate clearance between the bit shroud and the hole wall. This should forge a seal, thereby forcing the sample inside. If there is water in the hole, allow the hole to collar off as this helps to keep the samples dry, making them easier to transport and process. Conclusion

Water is forced down the hole of the hollow drill rods by a pump to keep the cutting tool cool. Such water returns to the surface from the outside of the rods with the sludge. With this arrangement it is possible to drill a depth equal to the length of one full rod at a time. Water flushing practically eliminates the use of a sludger. III.

Hole deviation is the unintentional departure of the drill bit from a preselected borehole trajectory. Whether drilling a straight or curved-hole section, the tendency of the bit to walk away from the desired path can lead to higher drilling costs and lease-boundary legal problems.
