Significant damage and downtime can result from rock falls and improper utilization of unspecialized equipment, such as rock drill rigs. As they are not designed for scaling, using drill rigs as scaling machines can result in both direct and indirect costs, including:

  • Unnecessary overuse of drill consumables (bits, rods, couplings, and adaptors)
  • Excessive boom maintenance from rock fall damage
  • Decrease in productivity as a result of drill rig downtime
  • Reduction of development advance or production tonnage from improper drill rig utilization

It is possible to use numerous pieces of equipment simultaneously in different headings and stages of the production cycle. Dedicated mechanical scalers enable the utilization of drill rigs in different headings while the mechanical scaler performs scaling functions, thereby increasing drill rig utilization.

Scaling is one of the more hazardous functions in the underground mining process. Because of the dangers in areas with unsupported back, rib, and face rock surfaces, proper mechanized scaling methods and equipment are critical to safety and productivity. Getman designs its purpose-built scalers to perform these rigorous scaling activities safely and effectively. Getman dedicates scaling machines to incorporate specific protection features for the scaler operator that may not be present in unspecialized equipment.
