Few tips to get the last achievement: add taverns on all empty spots on the map. and the big thing is that your population increase/day decreases with each day that you DON'T mine. it doesn't matter how much. as long as you do. so you can just use one little bomb a day and the people will be happy. Also hardware stores make the tents into larger houses, which increases the pop of each house. Hope this helps!
