Changes

To set up a mine where there is no exposed rock, you must first reveal the rock layer under the dirt layer. Dig at a reasonable distance above [[water]]. Keep digging in one corner until "You hit rock" or do not have enough skill to continue digging. Once you hit rock in one corner, then you must dig in all other corners until they have hit rock also. When you hit rock in all four corners, then the rock tile will be uncovered. If you lack the skill to dig in "such steep slopes", you could dig the nearby tiles down further as well, to reduce the slope to the corners you are working on.
