    In the following dissertation, the evaluation of risk with changing conditions over time is considered for a specific project - placing overburden into an active, open pit mine. The research focuses on the geotechnical components of risk with the goal of identifying whether and to what extent it is possible to place overburden on mined out ....Large open pit coal mines consume a significant volume of explosives in removing the overburden above thecoal. Many mines use cast blasting to reduce the quantity of waste material handled by draglines. This technique utilizes the explosive energy to cast a portion of the overburden into the spoil pile without the need for subsequent handling..and the mining sequence. Overburden mined from the Project will be placed directly as backfill, stored on temporary OSAs for use as backfill later, or stored in a permanent OSA. Most of the overburden mined will be transported directly from the active phase of mining to backfill the historical MCM open pits or into previously mined portions

A deposit that is deeper costs more in terms of time and resources to access than a deposit that is near the surface. Mining companies tend to use underground or open-pit mining methods to remove overburden and the ore see Figure L14.2 for an example of an open-pit copper mine.
