The project “Analysis of damage zones development depending on geology with the application of MWD technology for the prognoses of the extent in the remaining rock mass” was part of a PhD project at the Luleå University of Technology.
The study focussed at the possibility to predict blast damage and rock support requirements based on MWD. It showed the good possibilities to apply MWD in tunnelling, especially for rock support and characterising the rock mass more detailed. This work provides a framework for MWD data and its usage in practice for rock support installation. It takes the first steps towards correlating blast damage and rock mass properties based on MWD data. The work in this project was funded by the Rock Engineering Research Foundation (BeFo) and Swedish Blasting Research Centre (Swebrec).
