Technology from Rockma

ROCKMAs technology provides highly accurate and precise information about the rock mass. The drilling process and rock interpretation can be displayed in real time by the operator and by users of Rockma Software. Many types of drill rigs are equipped with a data acquisition systems, in those cases we use that the data from these systems. If the drill rig does not have these sensors pre-installed, we offer a complete system for this. The name or concept” Digital Mapping” comes from analyzing and presenting drill monitoring data. Drill monitoring can also be called MWD (Measurement While Drilling). Drill monitoring or MWD has different names for registration of drill parameters during rock drilling.

ROCKMA is a company that develops methods for analyzing these parameters and also develops software for graphical representation of the rock mass. The graphical representation is generated automatically and it is very user friendly. All data is handled is digitally. This is why the method is called” Digital Mapping”. ROCKMA can be used for all drilling methods, all brands and models. Many drill rigs can be delivered with MWD-systems (drill monitoring systems) often as an optional extra from the OEM. This is not necessary. ROCKMA has the possibility to sell and mount a complete logging system on all types of drill rigs. ROCKMA’s hardware (monitoring system) is optimized for the analysis and built on that basis. The analysis of drill monitoring data has been developed to generate very detailed rock mass information. The analysis is automatically generated and gives a foundation for a quick well-informed decision.

The rock properties we calculate and
present are normally:

  • The rock strength presented in MPa
  • Fractures, presented as fracture frequency (%) or RQD
  • Water conditions of the rock mass
  • Ore/waste
  • Rock formation and layers
  • Fractures and weak zones
  • Cavities
  • Blasting proprties
  • Grouting/injection classes
  • Rock support
  • Other properties can be calibrated against if reference data is available

Drilling process raw data, that we
use as a basis for our calculations
is often called:

  • MWD (Measurement While Drilling)
  • Drill monitoring
  • Other names can be used for the process of collecting drill data
