Interpreting data collected from the mining rigs provides challenge which is alleviated with help of visualization techniques. A good visualization shows all the relevant information at a glance and helps make decisions. In mining the information can be used for example to follow the concentration of the mined minerals, adjust drill settings according the rock properties, track wear of drill bits, make drill plans, detonation plans and bolting plans in order to ensure efficient and safe work. This thesis concentrates on finding the best ways to present the data from drilling machines. It has three main points: 3D visualization for analyzing large batches of collected drill data, real time drill visualization for use in the drill equipment during and immediately after the drilling and interpolation to find ways to interpret and expand from the data available. All the features in this thesis are built into a DrillGraph software, to be used as a basis for actual products.
