Advances in Drill Rig Deployed Radars

The deployment of geophysical instruments in underground mining is a rarity. The primary reason for this is that the implementation is often seen as cumbersome and time consuming by geologists and mine managers alike.<br>This paper explores the recent improvement in deploying borehole radar in hard rock mines. Firstly the paper examines the minimum gear needed to complete the task to simplify logistics. It then looks at the processing of data collected by borehole radar deployed on a core drill rig. The non-ideal stop-start motion of the deployment presents issues in the data quality. With the aid of an onboard accelerometer and a time logging based procedure, these quality issues are addressed by examining three different algorithms to process the data. The strengths and weaknesses of each are discussed, before concluding that an intelligent combination of velocity and statistical methods will reliably produce smooth “winch like’ data.
