Lecture-Opencast Mining Methods.pdf
Sequence of Development: Open pit mining normally involves the haulage of moderate to large amounts of waste and ore out of the pit for relatively long distances at steep grades. Because ore grades are typically low, and in most commodities, decreasing steadily, ratios must be held to modest levels (usually 0.8 to 4 m 3 /tonne). Thus most open pits are less …
