During the first three years of the minelife all the batteries will be charged on surface. There will be two batteries for each truck and the charge time is less than the battery life so the trucks can dump the ore or waste at an appropriate location on surface and change batteries before heading back underground.
Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface ...
