1. A1 drawing showing the long section and your plotted mass haul diagram (these should show all movements of materials and haul distances.
2. An eworks plan listing 3 main hauls, quoting the amount of material being moved, the haul including Ch to and from and distance, the plant utilized and the time to carry each haul out.
