All I know about gold mining is they have support pillars holding the mine up and they have tracks for the carts to wheel them up and down the track so they can move the stones and the gold, the people that are mining are wearing a helmet that has a flash light on it and the hat can protect you for any falling rocks for the top of the mine. Some time they get some dynamite and make a big hole for more mining. There are generators that give you power in the mine.
Discrimination mean's when there are a lot of people on a bus going on but he does not let you on because you are a different colour it is like racism.
I am going to make another blog posts but I'm going to have more information to write about.
