What Is Open Pit Mining? | An Underground Miner
Open-Pit vs. Strip Mining. Strip mining is a surface technique where workers clear vegetation, waste rock, and overburden from the ground. Typically, miners use these operations for extracting rock and coal from just below the surface. Open-pit mining differs as workers excavate large landscapes on deeper slopes, separated by "benches."

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.
