Mole Drills

Mole Drills can permanently move TL×10m³ of earth per hour per cubic meter of drilling equipment. Mass is equal to 1 tonne per cubic meter of drilling equipment. Price is MCr0.005 per cubic meter of drilling equipment. Power required is 0.0001 per cubic meter of earth moved per hour. Note: If the drill is not making a permanent tunnel, the underground speed of the drill increases tenfold.

"Historic" Mole Drills

The Space 1889 basic game allows the creation of mole drills of reliability one or two. This translates into vehicles capable of 16 or 32 kilometers of underground movement per day, or of constructing 1.6 or 3.2 kilometers of underground tunnels per day.  The following lists the mole drilling equipment which may be mounted on a vehicle to achieve these rates.

TL Type Volume Mass MW Price m³/hour Speed Bore
