Open Pit Mining Pros & Cons | Sciencing

Open Pit Mining Pros & Cons | Sciencing

Open-pit mining is much safer than shaft mining. In underground mining, the threat of a cave-in or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in cave-ins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.

The present invention relates to an open pit mining system. The system includes a material lifting machine configured to both: (1) excavate and remove overburden from an open pit of a mine; and (2) excavate and remove valuable material from the open pit. Advantageously, the machine removes the overburden waste material as well as the mined valuable material which would otherwise be .

Deep underground mines use refrigeration systems to provide a reasonably comfortable ambient environment to increase productivity and to maintain safety as a priority. Deep level gold mines maintain the environment at an acceptable temperature, i.e. 27�C. However, the increasing cost of doing so through refrigeration is becoming a significant factor in the economic viability of mines.

Reconveyed minerals are considered public domain minerals under the mining laws. Mining claims cannot be staked on acquired minerals; a prospecting permit (43 CFR 3500) is required to prospect for acquired minerals. Mining claims can be located on open public land administered by another federal agency (most commonly on Forest Service land).

Environmental Risks of Mining

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.

2.6 Underground mining. Coal extraction is of course less straightforward using underground mining techniques. The associated costs are higher, and these begin with the sinking of two shafts, an 'upcast' and a 'downcast' shaft for ventilation ().Sinking these to a depth of a kilometre may take a few years and during this time, no coal is extracted.
