METHOD OF OPERATING A ROCK BOLTING MACHINE

摘要

A method of installing a rock bolt is provided. A bolt hole can be formed by applying an insertion force to a drill rod and while the insertion force is being applied, applying a rotational force on the drill rod to rotate the drill rod and bore the bolt hole. A rock bolt can then be installed in the bolt hole by applying an insertion force to the rock bolt to insert the rock bolt into a bolt hole and while the insertion force is applied to the rock bolt, applying a rotational force on the rock bolt to rotate the rock bolt in the bolt hole. As the rotational force being applied to the rock bolt increases, the insertion force applied to the rock bolt can be decreased until no insertion force is being applied and the rock bolt has been torqued to a desired torque amount.
