Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa , a coal mine and its structures are a colliery , a coal mine is a 'pit', and the above-ground structures are a ' pit head '. In Australia , "colliery" generally refers to an underground coal mine. Coal mining has had many developments over the recent years, from the early days of men tunneling, digging, and manually extracting the coal on carts to large open cut and long wall mines. Mining at this scale requires the use of draglines , trucks, conveyors , hydraulic jacks and shearers.
Mining is the activity concerned with the extraction of minerals where as mining engineering is the practice of applying engineering principles to planning, development, operation, closure and reclamation of mines. Mining industry is in the lime light today, because it provides most of the raw materials required for the ever increasing demands of the society with regard to infrastructure, goods, services and energy.

A lthough the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically recoverable. This is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the coal mining industry create unique challenges as it endeavors to provide coal to the market at a competitive price, continually improve miner safety and health, and meet environmental and community requirements.

Там она и стала тем, кого японцы именуют хибакуся - человеком, подвергшимся облучению. Через девятнадцать лет, в возрасте тридцати шести лет, она лежала в родильном отделении больницы, страдая от внутреннего кровотечения, и знала, что умирает. Она не знала лишь того, что смерть избавит ее от еще большего ужаса: ее единственный ребенок родится калекой.
