In specific instances consideration of these may affect the choice of method or result in revision of pit limits established by cost estimates based upon stripping-ore ratios. Among the advantages of open-pit mining are its flexibility, the ability to obtain mass production with it, and the ease with which rate of production
  • Mine water management SRK

    1 Mining personnel have a different interpretation of the term “mine water management”.For the rock mechanics engineer it is the de-pressurisation of a slope in an open pit, for the metallurgist it might pertain to the water contained in the process circuit, and for the tailings engineer, the waste circuit.

  • Environmental Risks of Mining

    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.

    May 22, 2014· Mine dewatering techniques. Dewatering and groundwater control is an important part of many open pit and underground mines. Effective dewatering is a pre-requisite for safe and efficient mining. Poorly controlled groundwater will waste money, slow down mining and potentially cause adverse environmental impacts. However, techniques are available to successful control groundwater.

  • 1.1 PHASES OF A MINING PROJECT ELAW

    Because open-pit mining is employed for ore deposits at a substantial depth underground, it usually involves the creation of a pit that extends below the groundwater table. In this case, groundwater must be pumped out of the pit to allow mining to take place. A pit lake usually forms at some point in time after mining stops and
