Economical Drilling & Blasting PlanTarget is obtained via defining the cracking zone per charge (oversimplification) and visualisation of the situation for profile, aidrow(x) and field holes upon request.User can use the maximum charge allowable in that place. Attention: burden area ≠ cracking circle !

An Example of Drill Plan Design

• Round bottom design can be adjusted any time, many times rounded design will improve the advance

• Individual hole depth can be adjusted to specialize i.e bottom corner design



• Also orientation point tool is available (top and side view)

• Hole direction is done by setting the angle of few holes, direction-master holes.

• Other holes are interpolated according to them via the element



• Sequence defines the drilling boom and order.• Other holes are interpolated according to them via the element• Waypoints can be added to route the feed unit via an alternative way



• Roll-over angle defines roll-over joint angle for each hole.• Tools for roll-over angle interpolation and a ”hot spot” angle

definition for a group of holes are available



• Setting of the detonator number
