Jun 5, 2017 at 19:14 comment added Amadeus Most explosives in mining could also be replaced by mechanical, steam driven wedges; they can deliver huge amounts of directed fracturing force, which is all the explosion is doing. It is convenient to drill a hole and put a stick of dynamite in it; but a steam driven machine can hammer chisel a deep pocket into the rock, insert a hard steel wedge, and then hammer that in with more shock force than the stick of dynamite can deliver.
Jun 5, 2017 at 9:01 comment added Rekesoft Yep. I guess you can progress up to early XXth century civilization without electricity or explosives. Imagine a steampunk society, with smog-filled cities and everybody choking on its fumes. If we use electricity is not because is more efficient or cheaper, but because it's easy to transport long distance without significant loss, so we can have our polluting thermal generators away from the places we live in.
