The hole story: the benefits of drill and blast
2016-4-21 Changes in drillhole placement and blast timing can be performed before the drilling operator drills the holes. This approach allows for design changes before a single hole is drilled. If a high-precision guidance solution, such as Leica J2drill, is used to drill the holes, as-drilled data can feed into blasting simulators to adjust the blast design further before a shot is fired.
