Design of the final pit limit is thus governed not only by the ore grade distribution and the production costs, but also by the overall rock mass strength and stability. The potential for failure must be assessed for given mining layouts and incorporated into the design of the ultimate pit.

Assessment of heavy metals pollution in groundwater

The Golgohar iron ore mine in southern Iran is a large open pit that operates below the groundwater table. Dewatering operations and mining activities could be responsible for generating metal contamination in the groundwater of the area. In order to assess this, groundwater, soil, solid waste and rock samples were collected and analyzed for heavy metals.

Pit Slope Failure Problems in Goan Iron Ore Mines,

The problem of open pit slope stability is a matter of concern when the mining operations go deeper followed by weak strata conditions. In Goa iron ore mines the problem of slope instability has been faced by several mines, after the on-set of monsoon. A review of case studies available on the subject demonstrates that the ground displacement, stress redistribution, effect of ground water, low

Environmental Risks of Mining Massachusetts

2012-12-11 · Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
