You could say it's a second thing. Delver's species can get used to any gravitational force and can regenerate themselves thanks to the healing ability, that's why they're better off in the mine
Ahh, that is explains it
Wait, wholesomeness aside, I need more context on Delver's species. It's like the author told us that this guy has natural healing talent for healing but they decided that the species as a whole is better off going to the mine????
