How long does a mine last?

What is found in a mine?

By Lisa Algee. Mining is the extraction (removal) of minerals and metals from earth. Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and diamonds are just some examples of what is mined.

What is a mine layout?

Mine layout includes the size of rooms and pillars in the mines, but also includes factors like the number and type of entries, roof height, ventilation, and cut sequence.

How is a mine built?

It involves drilling a section of ore at the very bottom of the deposit and then blasting to make the roof collapse. Gravity then takes over, as the ore above the blast site fractures and collapses in succession as support is withdrawn. The collapsed ore is hauled out the mine for processing [source: Great Mining].

Whats it like in a coal mine?

Coal mining is dark, dirty, and dangerous work. It’s not for everyone — it’s for the few who love to descend into the bowels of the Earth to extract “black gold.” Even as they face the risk of mines collapsing, or catching on fire, or the long term health threats like black lung.

What locations are vulnerable in mining?

Unprotected, high value ecosystems are most vulnerable to the impacts from mining. Protected areas, areas of ecological value, and stressed watersheds are considered vulnerable.

What are the 3 types of mining?
