Mining equipment is very fun and generally huge. What I am sure most people don't realise is the amount of safety is built into any design constructed (especially here in Australia). There are safety factors upon safety factors upon safety factors included before anything is built. I am currently managing the design and construction of new infrastructure at a massive open pit mine in Australia. The shear magnitude of earth moving is unbelievable. Hear is an interesting fact I am sure will surprise most: Most gold mines have ore grades of about 5-7g/Tonne. That is 5g of gold for every 1 tonne of rock pulled out of the ground. Doesnt sound like much, but when a CAT 793C dumptruck is loaded with about 250T and the current gold price is as high as it is, you will see why even at 5g/Tonnes it is VERY profitable. Mining is all about efficiency, and optimising how much ore comes out of the ground. If you can get just 1 more dump truck per day, at today's gold price that equates to about $18million in revenue per year. If any entrepreneurs are looking for a market full of money, check out the gold miners. ;) edit: formatting.
