Coal Extraction and Black Lung :: Environment Energy Essays
Coal Extraction and Black Lung Coal is an indispensable fossil provide that is actually important to todays society. With out burn, one would realise to live without umteen of the luxuries we brook today. There would be no strikes to light a house, no movie cinemas, no electrical heaters, and no televisions or phones. Coal has many important uses, but most significancy in electrical energy generation, steel and cement manufacture, and industrial process heating. Coal provides over 23% of global primary energy need and generates about 39% of the lands electricity (Source 1). Coal is also used as dismiss for steam locomotives, to make synfuels, and in home heating. Some other various items made by combust ar insecticides, paint thinners, batteries, disinfectants, varnish and insulin. (Source 2) Coal, obviously, is very important to our society and we cannot do without it. The extraction of coal from the ground, however, can be a dangerous process that has serious health effects. The ways coal has been extracted from the ground has changed many times over time due to better tap techniques and different geological formations. In the early history of mining a technique called bell pitting was used where the coal was obtained by digging it from where it appears on the surface . This method was replaced by more high-octane methods. Today, the three methods of extraction are open cast, drift and deep mine (Source 3). These methods are not safe and many miners who work with these methods suffer many health problems. Coal miners suffer from many different health problems that are caused from mining. Among these diseases is the well known Black Lung. Black Lung is a legal circumstance describing man-made, occupational lung diseases that are contracted by prolonged breathing of coal mine dust. Call in miners asthma, silicosis, pneumonoultramicroscopicsilicovovanoconiosis, coal doers pneumoconiosis, or black lungthey are all dust diseases with the corresponding symptoms (Source 4). Black Lung usually effects workers who are over 50 and who have worked as a miner for most of their lives. The symptoms of black lung are coughing, spitting, and breathlessness. another(prenominal) symptom is that the lung has black pigmentation on it. In Severe cases, an enlargement and colour of the right typeface of the heart may occur. This is caused by chronic lung disease. The color on the heart may eventually cause right side heart failure.
