Bełchatw; coal Power plant and coal mine in Bełchatw, Poland. Stasisław Conversion In general, coal can be considered a hydrogen-deficient hydrocarbon with a hydrogen-to-carbon ratio near 0.8, as compared with a liquid hydrocarbons ratio near 2 (for propane, ethane, butane, and other forms of natural gas) and a gaseous hydrocarbons ratio near 4 (for gasoline). Coal is either extracted from deep inside the earth or removed from its surface. The former is known as underground mining, the latter as strip mining or mountaintop removal. Either process contributes a high level of damage to the environment: #12 Noise pollution

Conceptual Design and Feasibility Studies

Ausenco has successfully completed studies for clients all around the world. These include initial concept studies, pre-feasibility studies suitable for preliminary financial assessment to allow 'go/no-go' type decisions, and definitive studies used for assisting in the procurement of project financing.

Germany Converts Coal Mine Into Giant Battery Storage for In 2007 1 084 out of the 3 770 workers who died were from gas blasts Small mines comprising 90 of all mines are known to have far higher death rates and the government of China has banned new coal mines with a high gas danger and a capacity below 300 000 tons in an effort to reduce deaths a

Once coal has been uncovered by either an excavator or dragline, an excavator and truck combination are used to mine the coal. To ensure coal is mined optimally as well as accurate reconciliations, surveyors complete a pickup of both the top of the coal (roof) and once removed, the bottom of the coal

Coal mine gas (firedamp) is a problematic phenomenon associated with coal mining, as the gas can form explosive mixtures together with air. The main component of the primary coal seam gas is methane in a concentration of 90-95 % the gas develops during the geochemical conversion of organic substances to coal (carbonisation).
