Testing vibration isolators for underground raise bore drilling

Raise bore drills are used in underground mining to excavate a circular hole between two levels of a mine without the use of explosives. Current methods of operating these types of drills require operators to be at the drill location which places them at an increased risk for injury (i.e. rock failures, heavy/repeated lifting, pinch points, noise, dust, etc.). Underground operation of the bore drill would be safer if it included some automation of specific tasks, in conjunction with the ability to operate the drill remoted. A local company has designed an aftermarket system to add this functionality; unfortunately, the vibration of the raise bore is damaging the electronics and decreasing uptime. The proposed study is designed to determine which vibration isolators will best protect the electronic components of the automated drill rod changing system. Increasing the robustness and reliability of the automating the drill rod loading and unloading process would reduce the operator’s exposure to the occupational hazards encountered at the rock face.
