Underground Mining Methods and Equipment

1. Underground Mining Methods 1.1. Classification of Underground Mining Methods Mineral production in which all extracting operations are conducted beneath the ground surface is termed underground mining. Underground mining methods are usually employed when the depth of the deposit and/or the waste to ore ratio (stripping ratio) are

Establishing Total Airflow Requirements for Underground ...

Traditionally, ventilation requirements for modern, mechanized underground mines have been based upon the power of the diesel equipment fleet, with a multiplier (determined from empirical data collected and compiled over a long period of time or required by regulations) being applied in order to determine the total airflow volume requirements of

Geotechnical considerations in underground mines

underground mining operation should recognise, identify and address the geotechnical issues that are unique to a particular mine, in an appropriate manner, using current geotechnical knowledge, methodology, software and hardware. It will be appreciated that every mine does not necessarily have to apply all the techniques discussed in this guideline

Planning your mining career - Underground Training

Another misnomer about underground mining, in particular hardrock underground is that the mines are a confined environment so there is a need for a confined space ticket. This is simply untrue. If you have stood in the underground train stations in any major city then you have been in the equivalent of an Australian hardrock underground mine with regards to dimensions of the declines. The only ...

What is Underground Mining? (with pictures)

Proper ventilation and safety are essential for underground mining. One major need with underground mining is ventilation. Ventilation is necessary to remove dust, byproducts of combustion, and byproducts of explosions, along with gases which may be trapped in pockets inside the Earth.

mining - Underground mining Britannica

mining - mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on

Underground mining – block caving, bore hole, drift fill ...

Underground mining is carried out when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to work in. The mining company selects the best feasible way to get the minerals extracted out. Most mining is carried out using ...

Underground Mining Safety Equipment Checklist -

Underground mining operations around the world pose similar risks to worker safety and health. Though different techniques are used to extract base metals, precious metals, nonmetallic minerals, diamonds and coal, the hazards do not differ that much. The deeper the mine, however, the greater the risk. Safety Challenges in Underground Mines. According to the United States Department of Labor ...
