Those tend to use articulated dumpers, not the heavy haulers though. The heavy dump trucks can only go up a certain grade, which is why they're used in open cut mines, because they can make the haul roads whatever grade they want.

I worked at a company with 100 ton haul trucks in the Denver front range. Articulated haul trucks are great for rough terrain but the rigid frames can definitely climb. You have to manage grades with either truck though whether going up or down, just has to be addressed with good mine planning.

8 to 10% grade and plenty of mines use 240 to 320 ton trucks in these mines.
