It is well known that the Industrial Revolution, which began in Britain in the 18th century, and later spread to continental Europe and North America, was based on the availability of coal to power steam engines. International trade expanded exponentially when coal-fed steam engines were built for the railways and steamships. The new mines that grew up in the 19th century depended on men and children to work long hours in often dangerous working conditions. The goal of coal mining( rotary kiln ) is to obtain coal from the ground. Coal is valued for its energy content, and since the 1880s 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 States, United Kingdom, and South Africa, a coal mine and its structures are a "colliery". In Australia, "colliery" generally refers to an underground coal mine.
Coal mining has had a lot of 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, conveyor, jacks and shearers.
The trends of modern mining exploration are concentrated mining and intensive management.
First of all, mine production scale expands increasingly. The quantity of worldwide open coal mine shrinking sharply, while the annual output has increased rapidly.
The next one is the highly intensive management. Another important trend of concentrated mining is the concentrated share of coal production and marketing owned by large enterprise group. Among the world's largest 13 enterprise groups of mineral resources, there are 6 enterprise groups who possess tens of billions of dollars, 7 enterprise groups who possess several billion dollars. These large enterprise groups of mineral resources adopt globalized management and comprehensive management of various mineral resourcesIt is well known that the Industrial Revolution, which began in Britain in the 18th century, and later spread to continental Europe and North America, was based on the availability of coal to power steam engines.
