Once you've had enough [[Losing|fun]] to have a basic fortress working, it becomes necessary to dig down in search of ores, gems, water, etc. Exploratory mining attempts to dig out as little as possible in order to see as much as is possible, using clever digging patterns. | Once you've had enough [[Losing|fun]] to have a basic fortress working, it becomes necessary to dig down in search of ores, gems, water, etc. Exploratory mining attempts to dig out as little as possible in order to see as much as is possible, using clever digging patterns. | ||
