Coal Mining is a research technology in the Economy tree of the Research Center in Whiteout Survival.

Overview

Coal Mining increases Coal Gathering Speed. It is available in 5 tiers (Coal Mining I, Coal Mining II, Coal Mining III, Coal Mining IV, Coal Mining V), each with multiple upgrade levels.

Research costs include 5 resources: Resource, Meat, Wood, Coal, and Iron. Prerequisites require a specific Research Center level and, for higher tiers, completion of previous tiers. Construction times are base times and do not account for Research Speed bonuses.

-'''Coal Mining''' refers to the activity of gathering [[Coal]] from coal deposit tiles on the world map. Coal is a unique resource in Whiteout Survival because it serves a dual role as both a construction material and the essential fuel to power the [[Furnace]].
+'''Coal Mining''' is a [[Research|research]] technology in the Economy tree of the [[Research_Center|Research Center]] in Whiteout Survival.
 == Overview ==
-Coal is arguably the most critical resource in Whiteout Survival. Without Coal, the Furnace loses heat and your city's defenses against the deadly snowstorm weaken. Coal Mining ensures a steady supply for both the Furnace and construction projects.
+Coal Mining increases '''Coal Gathering Speed'''. It is available in 5 tiers (Coal Mining I, Coal Mining II, Coal Mining III, Coal Mining IV, Coal Mining V), each with multiple upgrade levels.

+Research costs include 5 resources: Resource, Meat, Wood, Coal, and Iron. Prerequisites require a specific Research Center level and, for higher tiers, completion of previous tiers. Construction times are base times and do not account for Research Speed bonuses.
-Coal tiles are scattered across the world map:

-== Importance of Coal ==
+== Coal Mining IV ==
-Coal is consumed in three major ways:
+{| class="wikitable"
-* '''Furnace fuel:''' The Furnace requires Coal to generate heat and protect the city from snowstorms. Running out of Coal stops heat production.
+|-
-* '''Construction:''' Building upgrades, especially at higher furnace levels, consume large amounts of Coal.
+! Level !! Prerequisites !! Resource !! Meat !! Wood !! Coal !! Iron !! Time !! Bonus !! Power
-* '''Research:''' Several research technologies in the Growth and Economy trees require Coal.
+|-
+| 1 || Research Center 22 Iron Output IV 1 || 930,000 || 930,000 || 180,000 || 46,000 || 12,000 || 07:46:40 || Coal Gathering Speed: 16.00% || 2,000
+|-
+| 2 || Research Center 23 || 1,300,000 || 1,300,000 || 260,000 || 65,000 || 16,000 || 11:40:00 || Coal Gathering Speed: 16.00% || 2,000

+| 3 || Research Center 24 || 2,700,000 || 2,700,000 || 550,000 || 130,000 || 36,000 || 1d 07:06:40 || Coal Gathering Speed: 21.50% || 2,687
+|}
-Because of this triple demand, Coal is typically the hardest resource to keep in surplus.

-== Tips ==
-* '''Prioritize Coal over other resources:''' Never let the Furnace run out of Coal — it is a city-wide emergency if it does.
-* '''Keep a Coal buffer:''' Always maintain at least a 24-hour supply of Coal for the Furnace to avoid emergencies.
-* '''Mine Coal constantly:''' Unlike other resources, Coal has dual consumption, so it depletes faster.
-* '''Upgrade Coal production buildings:''' Passive Coal generation helps supplement gathering runs.
-* '''Coordinate in alliance:''' Alliance-controlled territory near Coal tiles gives your whole alliance better access.
