 · Open-pit mining requires creating a large pit in the ground from which the miners extract the needed material. This is one method miners may use to extract silver from the earth. The other technique is underground silver mining. Occasionally, removing a hilltop with explosives to expose the rocky materials beneath is the first step in creating ...

 · 1.2. Open Pit vs. Underground Mining Methods While most mineral deposits can be mined by either surface or underground methods, some minerals can only be recovered in a hybrid manner, usually by initial extracted by open pit mining, followed by underground methods. Here, a brief comparison is made

As open pit mines continue to grow deeper and productivity continues to increase, the management of air pollution can become challenging. The natural wind flow in open pit mines is generally recirculatory. This recirculation can trap harmful aerosols and gases in open pit mines. This problem is exacerbated as the depth of the pit increases.

When compared to underground mining methods, open pit surface mining is considerably more efficient. 1. Increased Efficiency. One of the biggest benefits open pit mining produces is the growth in the overall efficiency when compared to deep-shaft mining methods. Mining occurs on the surface, so there aren't any space restrictions arising from ...
