KSJ21-CYTC115 Hydraulic mining 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 3.5m-5m.


  • The automatic rod-changing system has a storing capacity of 27 drill rods and the drilling depth can reach as far as 42 meters.
  • The front and rear of the advancing beam are fitted with hydraulic supporting cylinders for smooth drilling. It is fitted with the hydraulic guiding cylinders and thus ensures the drilling straightness as good as possible.
  • The trolley-type workbench with a good sight is adopted; and the wireless remote controller can serve as an option.
  • The articulated mining chassis of closed hydraulic drive 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.
