A major element of the mining process is breaking up the rock. This fragmentation is accomplished by detonating explosives set in blastholes. The heading, or rock face to be blasted, is typically 40-feet wide by 20- to 25-feet high. A designed pattern of 40 to 50 horizontal drill holes two inches wide by 12- to 14-feet deep, are bored into the ...

The limestone averages 18.3 m (60 ft) in thickness, with mining planned in two lifts (i.e., initial development and benching). The height of the initial development was 7 m (23 ft). Secondary bench mining removed an additional 9.1 m (30 ft) from the floor, resulting in a total planned mining height of 16.2 m (53 ft).
