Tunnel Logistics — Tunnel Conveyor Capacity
Tunnel Conveyor Capacity for TBM drive planning.
Continuous conveyors delete the train-cycle ceiling — advance becomes geology-limited again. The surge factor is the design detail: a belt sized to the AVERAGE chokes during every full-power push, and a choked belt stops the machine as surely as a derailed train.
Formula
Note: Planning-level tunnelling estimate — actual TBM performance is set by detailed geotechnical baseline data, machine design and the contractor's means & methods. Use for feasibility framing only.

About Tunnel Logistics — Tunnel Conveyor Capacity
Tunnel Logistics — Tunnel Conveyor Capacity computes the governing relationship ROP_max = (t/h ÷ ρ ÷ surge) ÷ m³-per-metre live as you type. Continuous conveyors delete the train-cycle ceiling — advance becomes geology-limited again. The surge factor is the design detail: a belt sized to the AVERAGE chokes during every full-power push, and a choked belt stops the machine as surely as a derailed train. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Tunnel Logistics — Tunnel Conveyor Capacity
- 1Enter your values — Belt rating, Loose muck density, Loose muck per metre, Peak/average factor (sensible defaults are pre-filled).
- 2Read the live results: Belt-limited boring rate.
- 3Check the "with your numbers" line to see ROP_max = (t/h ÷ ρ ÷ surge) ÷ m³-per-metre substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Tunnel Logistics — Tunnel Conveyor Capacity?
