Design of an open-pit gold mine by optimal pitwall profiles
INTRODUCTION. In open-pit mining, there is a clear trend of excavating mines of increasing depths (Figure 1a).Owing to the increased efficiency of mining equipment and improved exploration techniques and technology, the ore bodies left to be exploited are deeper (Figure 1b).The deeper a mine is, the higher the effect of pitwall …

Open Pit Mining
Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.
