Open Pit Mining an overview ScienceDirect Topics

8.2.3.1 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.

Top 10 deep open-pit mines Mining Technology

2021-2-21  Nanfen open pit iron mine, located in Nanfen district of the Liaoning province, China, is approximately 500m deep. It is one of the largest open-pit metal mines in China. Nanfen open pit mine is owned and operated by Benxi Iron and Steel Corporation (Benxi Steel). The mine produced more than 100 million tonnes of iron ore in 2011.

Application of open-pit and underground mining

Given the conditions of residual coal from the boundary of a flat dipping open-pit mine, which uses strip areas mining and inner dumping with slope-covering, we propose an open-pit and underground integrated mining technology for residual coal of end slopes. In the proposal a conveyance road and ventilation conveyance near the slope are built
