Applications

The KSJ21-CYTC115 Hydraulic long-hole drilling rig is mainly used for blast drilling of medium-length hole mining and supporting drilling of anchor cable. Both the applicable height and width of tunnels fall in the range of 2.9m-5.2m. width 2.8-4.5m. The support for the drill boom is capable of 360-degree rotation. In combination with swing boom and translational guide rail, it is capable of 360-degreee drilling, thus meeting the requirements of various mine drilling.

Performance Characteristics

  • Economical drilling depth up to 35meters, optional 27+1 automatic receiving and unloading rod modules (drill pipe length 9000mm, automatic receiving rod depth 25meters), to chieve single-person operation.
  • Heavy-duty aluminum alloy medium and deep hole special propulsion beam, front and rear hydraulic center support, ensure the stability of drilling process. With rod oil cylinder, maximum straightness of borehole is maintained.
  • The trolley-type workbench with a good sight is adopted; and the wireless remote controller can serve as anoption.
  • The articulated mining chassis of closed hydraulic drive, the rig is 1.6m wide, is suitable for small and medium-sized tunnels.
  • The stepped piston is used for the high-frequency impacting rock drill and this can improve the transmission efficiency of ipacct wave and drilling speed and reduce the consumption of drilling tools and make it in good condition.
