Main Components
  • Feeding system
    Feeding system
    Stainless steel-made and wear-resistant cover is adopted to protect the feeding beam and drill strings.
    The rotation unit delivers large torque and high reduction ratio. With a special design, it reduces the possibility of getting struck and the rotation speed is adjustable based on rock characteristics.
    Imported seals ensure reliable sealing performance and long service life.
  • Automatic rod exchanger
    Automatic rod exchanger
    All the functions, such as rod storage, rod loading and unloading, movement of the mechanical clamps, can be controlled easily with one single joystick.
    Adopting a clamping design, the changer can easily unload the rod and increase work efficiency.
    With one button, the system can automatically change rods.
  • Air compressor
    Air compressor
    Atlas Copco two-stage air compressor with strong air output is reliable and powerful. It is applicable to rock formations of various hardness and offers high penetration rate with ease.
  • Engine
    Engine
    High-power turbocharged direct injection engine with water cooling function delivers reliable performance and is energy-saving.
    The three-stage air filter system ensures intake of clean air and greatly reduces the engine failure rate.
  • Control panel
    Control panel
    The control valves adopt a prior hydraulic control system that feature flexible control, reliable performance and easy maintenance. It greatly facilitates the operation of the rig.
    The control system enables rapid feeding and lifting. The feeding force is adjustable based on different environments, which reduces drilling time and increases efficiency.
  • Cabin
    Cabin
    The FOPS-certified enclosed cabin is equipped with an air conditioner, which meets the labor protection standards of the US and Europe.
    A large safety window offers a wide view which enables operators to better control the rig.
  • Control system
    Control system
    The dashboard clearly displays the operational parameters, prompts and warning in real time for convenient monitoring and precise hole drilling.
  • Dust Collector
    Dust Collector
    The hydraulic dust collector with a sliding cover that collects dust delivers stable and efficient performance, which extends the rig’s service life and ensures a clean working environment.
  • Undercarriage
    Undercarriage
    The undercarriage adopts a robust design of four wheels and one track. Widened tracks enable smooth travelling and strong climbing capability to support heavy-duty drilling jobs.
    4 leveling jacks are designed to angle to 10 degrees left and right to support drilling work in rough terrains. It supports high and low speed shifts to realize flexible movement between drilling sites.
    With a ground clearance of more than 400 mm, it can travel through rough terrains without colliding with the ground.

As mining technology is developed, the number of drilling methods is increasing. The common drilling methods include auger drilling, rotary air blasting, reverse circulation drilling, diamond core drilling, blast hole drilling and hydraulic rotary drilling.

The DTH system is applicable to a wide range of rocks, including soft, medium hard and extreme hard rocks, and various formations.
