Products /  Heading machines /  2KV-A /  Description


The 2KV-A raise-borer is designed for driving vertical and inclined rise workings in rocks with an ultimate strength σcomp= 210 MPa  in mines with no hazardous concentrations of gas and dust. Raise workings are driven by boring a pilot hole from top to bottom until entry to the lower level and by boring a drift across the entire section from the bottom upwards. Rock is broken by roller-bit drilling.
