  • Underground Mining for Meeting Environmental Concerns A

    Underground mining can be considered to be more acceptable than surface mining from environmental and social perspectives since, it often has a smaller footprint than an open pit of comparable capacity. The main advantage of underground mining compared to surface mining is that in general only the ore is extracted and waste rock is left behind.

  • Ground Water Problems in Open Pit and Underground Mines

    Ground water constitutes a significant operational problem and potential hazard in open pit and underground mining. The pressure of ground water in geologic discontinuities adversely affects the safety of height and slope angles of open pit mines, justifying measures to reduce ground water pressures in their vicinity.

  • Block Caving Ground Truth Trekking

    Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.
