Mine Blast Planning and Safety
How a mine plans and carries out a blast safely: drill pattern design, explosive loading, area clearance, the blast, and post-blast checks.
Drawing diagram…
What this diagram shows
- The blast area is cleared and guarded before firing
- Misfires are handled by a set procedure
- Vibration is measured to protect nearby villages
Prompt used
Blast workflow: the engineer designs the drill pattern and charge per hole, drills are completed and hole depths checked. Explosives are loaded under supervision and the blast plan is approved by the mine manager. Sirens sound, the danger zone is cleared and guards posted. The shot-firer fires the blast. After the fumes clear, the area is inspected for misfires; if any, the misfire procedure is followed. Ground vibration and noise readings are recorded before the all-clear.

Mine Fleet Management System
A fleet management system for an open-pit mine: dump trucks and shovels report position and payload, a dispatch engine assigns loads, and a control room watches production live.
Haul Truck Cycle
The states of a mining haul truck in each load-and-dump cycle, used by dispatch systems to measure productivity and waiting time.
Underground Mine Communication Network
How an underground mine keeps people connected and safe: leaky feeder radio, Wi-Fi, gas sensors and personnel tracking tags, linked to the surface control room.
Ore to Metal Material Flow
How mined ore becomes finished metal in an iron and steel chain, in thousand tonnes per month, showing where material is lost.
Smelter Process Control Deployment
Where the control systems of a metal smelter run: field instruments, PLCs and a DCS in the plant, a historian, and a separate business network behind a demilitarised zone.
Chemical Batch Traceability
Tables that trace a chemical product batch back to its raw material lots, process steps, quality tests and customer shipments, for recalls and audits.
