MINING

Mining refers to ore extraction. Mining is the industrial process of removing a mineral-bearing substance from the place of its natural occurrence in the Earth’s crust. The term “mining” includes the recovery of oil and gas from wells; metal, non-metallic minerals, coal, peat, oil shale and other hydrocarbons from the earth.

Mining can be done either as a surface operation (quarries, opencasts or open pits) or by an underground method. The mode of occurrenceof the sought-for metallic substance governs to a large degree the type of mining that is practiced. The problem of depth also affects the mining method. If the rock containing the metallic substance is at a shallow site and is massive, it may be economically excavatedby a pit or quarry-like opening on the surface. If the metal-bearing mass is tabular, as a bed or vein, and goes to a great distance beneath the surface, then it will be worked by some method of underground mining. Working or exploiting the deposit means the extraction of mineral. Mine workings vary in shape, dimensions, location and function.

Depending on their function, mine workings are described as exploratoryto find or prove mineral, and productive when used for the immediate extraction of useful mineral. Productive mining can be divided into capital investment work, development work, and face or production work. Investment work aims atensuring access to the deposit from the surface. Development work prepares for the face work, and mineral is extracted (or produced) in bulk.

Say whether the following statements are true (T) or false (F). If false, correct them according to the text.
