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.
Coal seam gas is simply natural gas sourced from coal deposits. Natural gas â or methane â is found in several different types of rocks, including coal seams, sandstones and shales.Coal seam gas is trapped in coal formations, typically 400-1000 metres underground, although it can be found at depths up to 1200 metres.oal seam gas is simply natural gas sourced from coal deposits.
