Coal Mine

Produces Coal. Delivering Tools boosts production.

Production recipe

Required inputs

No required input listed.

→

Output

16 Coal units

Baseline: 20 cycles per default simulation year. Actual throughput depends on deliveries and operating conditions.

Optional cargo boosts

These inputs support a separate boost cycle; they are not required ingredients in the production recipes.

Boost consumption

13 Tools units per boost cycle

Baseline: 4 boost cycles per default simulation year. Production multiplier: 1.5–2.5× while active. Delivery conditions affect the boost; this is not a guaranteed annual shipment total.

Restrictions

Economies: Temperate, Dry, Tropical, Subarctic

Storage

Tools: 100 units (Input stock)
Coal: 400 units (Output stock)

Production

Recipe cycle frequencies accompany each production recipe. Actual output depends on available inputs, productivity boosts and plots.
Cargo boosts improve productivity and combine with worker boosts.
Worker boost: at least 10 workers arriving by a passenger line within two default simulation years; productivity increases by 1.5–2.5× while the condition is met.
Plots can expand around the industry; occupied land and removed plots limit output. Available plots depend on the placed instance.
