The construction cycle is the control system.
Probe / drilling → charging → blasting → defuming → mucking → scaling → support → grouting / treatment → next advance.
Decision variables
- Cycle productivity and equipment balance
- Ventilation and defuming adequacy
- Ground and water behaviour
- Support timing and performance
- Access and logistics constraints
- Gas / fire / inundation / operational triggers
