Look to flexibility in mine ventilation. Investigate applying Ventilation on Demand (VOD) principles. Apply air where it is needed, when needed instead of fixed airflow quantities at all times. There is considerable monitoring and control capability in the industry, use it to your advantage (Allen, 2008).

Feb 25, 2015· For those who are unfamiliar, strip mining is a form of surface mining that focuses on the collection of tar sand and coal, which both rest somewhat close to Earth's surface. Those who support strip mining point to the increased ease of access and all of its attendant benefits. Detractors point to the controversies surrounding this method.
Rail haulage once ruled underground mining but lost its dominant position due to the flexibility and investment advantages of truck or conveyor haulage. New locomotive technology makes a strong case for returning to rail—and not just for the largest mines. By Markus Dammers, Dr. Gregor Brudek, Matthias Pütz and Dr. Andreas Merchiers

Ore:a mineral deposit that has sufficient utility and value to be mined at a profit. Gangue:the valueless mineral particles within an ore deposit that must be discarded. Waste:the material associated with an ore deposit that must be mined to get at the ore and must then be discarded. Gangue is .
Although underground mining is a less environmentallydestructive means of gaining access to an ore deposit, it is often more costly and entails greater safety risks than strip mining, including openpit mining. While most largescale mining projects involve openpit mining, many large underground mines are in operation around the world. Reworking of inactive or
Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest underground copper mine.
