Best practices: Drilling and blasting : Pit & Quarry

Blasting contractors should lay out the drill pattern based on a surveyed profile of the face. At a minimum, a profile survey should be done after drilling and before loading so that the proper explosive load can be determined for each blast hole based on the survey and drill log. A best practice would be to profile both before and after drilling.
