  1. Concept of DTH Drilling: DTH drilling means that rocks and substrates are drilled using a fixed bit and a rotary system. This bit moves downward with high pressure and speed, and with the assistance of a lifting mechanism, cut materials are conveyed out of the hole.
  2. Components of DTH System: The DTH system consists of several main parts, including:

DTH Bit: The drilling bit that is connected to the system and where the drilling action takes place. Intermediate Pipe: A pipe used for conveying air and water to the bit. DTH Hammer: This part strikes the bit with high pressure and small chips, playing a crucial role in drilling.

3. Advantages of DTH Drilling:

High Speed: DTH drilling enables faster penetration into the earth’s depths. Greater Depth: Due to the higher impact power and the ability to use different bits, drilling depth is increased. Lower Cost: Considering the high efficiency of DTH drilling, drilling costs are reduced. Better Rock Control: This technology is well-known as a widely used method for drilling hard rocks. Due to precise control over the drilling bit, it is suitable for drilling in various and dense rock environments.

  1. Applications of DTH Drilling:

Oil and Gas Well Drilling Water Well Drilling Mining Operations Construction and Civil Engineering Ultimately, drilling using DTH technology is one of the effective and efficient methods for drilling in various ground conditions. With its high speed, greater depth, better rock control, and lower cost, it stands as one of the primary choices in the drilling industry.
