The advancement of the steam engine dramatically improved the efficiency of coal mining during the Industrial Revolution making coal a cheaper more abundant and easily available source of energy. This resulted in labor conditions that triggered influential unions and in pollution that sparked the environmental movement.
Evaluate the effect the rising use of coal had on development and industry
Coal is a combustible black or brownish-black sedimentary rock occurring in layers or veins called coal beds or coal seams. Coal is composed primarily of carbon along with variable quantities of other elements chiefly hydrogen sulfur oxygen and nitrogen. A fossil fuel coal forms when dead plant matter is converted into peat which in turn is converted into lignite then sub-bituminous coal bituminous coal and lastly anthracite. This involves biological and geological processes that take place over time.
Coal was so abundant in Britain that the supply could be increased to meet the rapidly rising demand. In 1700 the annual output of coal was just under 3 million tons. Between 1770 and 1780 the annual output of coal was some 6.25 million long tons or about the output of a week and a half in the 20th century. After 1790 output soared reaching 16 million long tons by 1815. By 1830 this rose to over 30 million tons.
The development of the Industrial Revolutionled to the large-scale use of coal as the steam enginetook over from the water wheel. In 1700 five-sixths of the world8217s coal was mined in Britain.
The introduction of the steam pump by Thomas Savery in 1698 and the Newcomen steam engine in 1712 facilitated the removal of water and enabled shafts to be made deeper so more coal could be extracted. A number of Newcomen engines were successfully put to use in Britain for draining hitherto unworkable deep mines with the engine on the surface. These large machines requiring a lot of capital to build were extremely inefficient by modern standards but greatly increased the scope of coal miningwhen located where coal was cheap at pit heads.
Despite their disadvantages Newcomen engines were reliable and easy to maintain and continued to be used in the coalfields until the early decades of the 19th century. The next major step occurred when James Wattdeveloped 17631775 an improved versionof Newcomen8217s engine. Boulton and Watt 8216s early engines used half as much coal as John Smeaton8217s improved version of Newcomen8217s. Watt8217s ten-horsepowerengines could powera wide range of manufacturing machinery and be sited anywhere that water and coal or wood fuelcould be obtained.
Coal mining remained very dangerous due to the presence of firedamp in many coal seams. Some degree of safety was provided by the safety lamp invented in 1816 by Sir Humphry Davy and independently by George Stephenson. However the lamps proved a false dawn because they became unsafe very quickly and provided a weak light. Firedamp explosions continued often setting off coal dust explosions so casualties grew during the entire 19th century. Conditions of work were very poor with a high casualty rate from rock falls.
Mining has always been dangerous because of methane gas explosions roof cave-ins and the difficulty of mine rescue. The worst single disaster in British coal mining history was at Senghenydd in the South Wales coalfield. In 1913 an explosion and subsequent fire killed 436 men and boys. The Courrires mine disaster Europe8217s worst mining accident caused the death of 1099 miners in Northern France in 1906.
The focus of the mining industry is shifting towards potential new resources in remote areas as a result of decreasing ore grades. Remote sensing technology is an effective and widely established analytical method for geology and mineral exploration and has proven extremely beneficial by providing access to dangerous or previously inaccessible mineral deposits.

UK-based African Minerals AML through its subsidiary Tonkolili Iron Ore is developing the Tonkolili iron ore mine in Sierra Leone West Africa.
Mining lease for the project was approved in August 2010 and the first phase development commenced direct shipping iron ore production in November 2011. Construction of the concentrating facility for the second phase development of the project is expected to commence by the end of 2014. Production is expected to start from 2016.
Tonkolili mine is expected to have an operational period for more than 60 years. AML owns 75 stake in the mine while Shandong Iron and Steel Group SISG own the remaining 25.
Tonkolili iron ore deposit is located within the Sula Mountain range and forms part of a banded iron formation BIF featuring a north east-south west trending magnetic anomaly. The mine contains four contagious ore bodies Simbili Marampon Numbara and Kasafoni.
Each of the ore bodies is open at depth and characterises primary magnetite mineralisation underlying the secondary hematitegoethite style mineralisation.
