。[Detailed Description of the Invention] [Object of the Invention] Industrial Applications The present invention is applicable to the construction of utility pole piers on the ground and to prevention of landslide collapse. This relates to a rock drilling method suitable for excavating relatively large-diameter holes, such as when establishing piles for construction. In order to drill a hole with a large diameter, a rock drilling machine equipped with several small-diameter drill hammers is used to perform the drilling process several times to obtain a large-diameter hole.
