MPL-22 hole drilling and loading machine is designed for drilling blastholes and loading of muck at the drill and blast method of driving horizontal and inclined up to ±12º mine galleries in rocks with UCS up to 100 MPa in mines hazardous on gas (methane) and coal dust.


  • MPL-22 – with drilling rig and articulated scraper conveyor less belt stage loader
  • MPL-22 -01 – with drilling rig and fixed short scraper conveyor and belt stage loader
  • MPL-22 -01 – with drilling rig and fixed short scraper conveyor and belt stage loader
  • PL-22 -03 – without a drill rig and with fixed short scraper conveyor and belt stage loader.
