    摘要: Apparatus and methods for preparing a blast hole in a rock face during a mining operation are disclosed. An exemplary method comprises: deploying a first tool toward the blast hole in the rock face via a common tool outlet of a feed unit using a first tool station of the feed unit; retracting the first tool from the common tool outlet using the first tool station of the feed unit and retaining the first tool in the first tool station; and while the first tool is retained in the first tool station, deploying a second tool toward the blast hole in the rock face through the common tool outlet of the feed unit using a second tool station of the feed unit.
