Coal mining
Coal mining is the process of extracting 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 Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit ...

Arduino Sound Level Meter
· Measure Sound/Noise Level in dB with Microphone and Arduino. Noise pollution has really started to gain importance due to high population density. A normal human ear could hear sound levels from 0dB to 140dB in which sound levels from 120dB to 140dB are considered to be noise. Loudness or sound levels are commonly measured in decibel (dB), we ...

The Dominican coal market shrank modestly to in, remaining constant against the previous year. This figure reflects the total revenues of producers and importers (excluding logistics costs, retail marketing costs, and retailers' margins, which will be included in the final consumer price). In general, consumption saw a pronounced decrease.

Decibel
The decibel may be an unfamiliar scale to some but typically we deal with noise levels between 30 and 100 dB(A) 1 in everyday life. Noise levels below 35–40 dB(A) are usually necessary for a good night's sleep; a busy office may be about 60 dB(A) while the noise level on a footpath beside a busy road might be approximately 75 dB(A) and a departing jumbo jet may result in .

CO2 emissions by fuel
At a global level we see that early industrialisation was dominated by the use of solid fuel—this is best observed by switching to the 'relative' view in the chart. Coalfired power at an industrialscale was the first to emerge in Europe and North America during the 1700s.
