Over time, the extra work and pressure can stiffen blood vessels, leading to high blood pressure, heart attack, and stroke. It can also lead to heart failure. There is also some evidence that too much salt can damage the heart, aorta, and kidneys without increasing blood pressure, and that it may be bad for bones, too. High blood pressure is a leading cause of cardiovascular disease.
CMM is a mixture of methane & air released during the process of coal mining and must be vented for safety reasons. Methane has significant effects as a greenhouse gas being 21 times higher than that of carbon dioxide, therefore its capture and use in gas engines has significant environmental benefits.
Methane (CH 4) is a gas formed as part of the process of coal formation â coalification. When coal is mined methane is released from the coal seam and the surrounding disturbed rock strata.Methane can also be released as a result of natural erosion or faulting.The methane content in coal seams generally increases the deeper the seam, and also with age.ethane is released during the process of extracting coal in both surface and underground mining. The released methane then mixes with air, which becomes highly explosive if methane concentration levels reach 5-15%. Methane explosions are devastating, causing significant loss of life and damage to property.
