4:30pm Shift finished!
The drill and blast engineer puts the finishing touches on tomorrow’s blast design and decides to check emails before logging off for the day. There is an email from operations. Blast requirements have changed. Two smaller blasts are being combined so a revised design is needed for the blast crew.
This isn’t unusual - mine sites are dynamic environments with designs and plans constantly changing. Using conventional drill and blast software to create the new blast pattern would mean a long night at the desk. And an even longer one if relying on spreadsheets! Fortunately this engineer uses Maptek BlastLogic.
BlastLogic is a paperless system. Data is immediately available where it is needed.
Multiple users can access the same, up-to-the-second data. Recalling previous blasts for analysis is instant. The dynamic 3D environment helps make obvious connections between drilling, designs and patterns. Changes can be made quickly and easily.
The drill and blast engineer opens the blast design to make the required changes. Drilling data is imported automatically from the drill navigation system and immediately matched to each design hole before updating the charge plan with one click.
A catalogued blast blast with similar conditions is referenced to check its performance. Different scenarios are considered before the optimal charge plan is selected.
There is a fault running through this bench. The engineer checks and tweaks the design row-by-row using the cross-section profile tool. The charge plan is updated and reviewed in minutes.
4:45pm New design finished!
The new blast design is signed off and shared to the BlastLogic tablets ready for the blast crews in the morning.
NEXT MORNING ...
5:30am The blast crew arrives and is briefed on the day’s work. Many of the holes from the second, smaller blast have not yet been checked for depth and water.
Fortunately the BlastLogic tablet allows the crew to dynamically update charge plans hole-by -hole as they input new dipping data.
6:05am Connection to the network is not reliable in this part of the pit, but that won’t slow down the loading of holes as the data is cached on the BlastLogic tablets.
Some holes are identified as wet. The charge plan is instantly adjusted according to the parameters defined by the engineer in the BlastLogic charge rules.
12:40pm Four explosive trucks and 2 stemming trucks are involved in today’s work. The loading by each truck deck-by-deck is instantly recorded and synchronised to the BlastLogic system so progress can be tracked across the blast team.
The team has worked together over many blasts. BlastLogic promotes clear communication and aids productivity.
The digital data is easily matched to the reality on the ground so shotfirers, truck operators and support crew all work in harmony. Charge plans are continually updated and able to be tracked, underpinning the accuracy and efficiency of the blast process.
Observations recorded against the blast indicate that the blast has been successful. There is no time to celebrate; the team is already working on the next pattern.
BlastLogic automatically catalogues daily activities and results. They can be easily recalled to help improve future blasts. Reports are immediately generated and circulated to management.
