  • Overburden calculations compared to design geometry


  • The rock mass hardness is estimated based on a normalized and filtered penetration rate. The normalization process includes correction of varying average penetration rate, varying feeder- and hammer pressure at the start of the drilling, and filtering irrelevant data.
  • The rock mass fracturing is estimated based on a variance calculation of the normalized penetration rate and rotation pressure. A gliding root mean quare value catches sudden changes in drillability within the rock mass.
  • The water model is based on a normalized water flow. The normalizing corrects varying average water flow, incoming pressure and pressure drop in drill rods. Rapid changes in the amount of water is detected by calculating a root mean square value of the normalized water flow.
