Our DTH150  mining  down-the-hole  drill  is  mainly  used  for  deep  hole  drilling  in  non-coal underground mines, tunnels, water conservancy and other geotechnical engineering for all-round large-diameter and high-section caving mining method, especially  for the drilling of annular holes in underground stope. It can greatly improve the height of mine section and greatly reduce the workload of mining.
Technical features:

☆ It has an efficient down-the-hole drilling system, which is easy to operate, has strong reliability, high perforation efficiency, good hole forming quality and compact structure.   ☆ Powered by electricity, it has low operating cost and low energy consumption.

☆ The key hydraulic parts of the hydraulic system are imported brands, with energy saving, high efficiency and reliability.

☆ The propulsion device adopts V-shaped guide rail structure, the drilling accuracy is improved, and the drilling deviation rate is less than 1%.

☆ In the process of rock drilling, the impactor is close to the drill bit and sneaks into the bottom of the hole. When working, the impact energy loss will not occur because of the  connection of many drill pipes. No matter what the hole depth is, the drilling speed is constant. The drilling depth can reach 100 meters.

☆ High pressure drilling, drilling speed is 0.2m ~ 0.3m per minute. ☆ The 360° rotary drilling frame can realize annular hole drilling.

☆ Stable and reliable multi-point support mechanism, high drilling precision.

☆ The four-wheel independent drive, the drilling rig has strong walking ability, can turn 360° in situ, and has superior mobility and fast walking function.

☆ The rotary head directly driven by low speed and high torque hydraulic motor has simple and reliable structure. The sealing device of rotary head effectively improves the sealing

performance of high pressure gas and water, and the rotary head has long service life and simple maintenance.

☆ Different specifications of rotary motors are selected, and the drilling hole diameter can be selected fromφ76 to φ254.

☆ The electronic pulse oil injection system makes the impactor be effectively lubricated and has a long service life.

☆ The hydraulic d isassembly rod system reduces labor intensity and saves auxiliary operation time.

☆ The drilling operation realizes long-distance operation.

☆ The electrical system has grounding protection, short circuit protection and overload protection device.

☆ Can be pulled while long-distance transfer.

☆ Has obtained the "Mining product Safety Certification Mark Certificate".
