The technique of line drilling is among the earliest controlled blasting method utilized in mining operations where rock mass is of homogeneous nature [13]. The purpose of line drilling is to create a plane of weakness by drilling closely spaced, small diameter holes along the perimeter of the rock mass which needs to be blasted (Figure 1).
