CDC - Mining - The Effect of Ventilation on Spontaneous

Ventilation plays an important role in the spontaneous heating of coal in an underground coal mine. If the ventilation rate is too high, heat is carried away by convection. If the ventilation rate is too low, the reaction rate becomes oxygen-limited. The effect of ventilation on the spontaneous heating of coal was investigated in an isothermal oven in this study

Lesson Plan | Fossil Fuels: Chocolate Chip Mining

Mining. Mining is the process of extracting coal, oil, and natural gas from the ground. Strip mining (also known as open cast, mountaintop, or surface mining) involves scraping away earth and rocks to get to coal buried near the surface (Greenpeace, 2010). This often has significant impact on the surrounding land, plants, and animals

Mines collect and conduct water that is in contact with pyrite, a mineral that produces iron and sulfuric acid when exposed to air and water. Limestone is often used to mitigate the effects of pyrite on water

With the gradual depletion of coal resources in eastern China, coal mining has been expanded in central and western regions, and thick coal seams are widely present therein. 1 At present, the maximum mining height reaches 8.8 m, and the geological conditions of large-mining height and a complex key layer are often associated with gas, and the incidence of gas

Coal is a kind of sedimentary rock with obvious beddings, especially for normal coals. 1, 2 The existence of beddings weakens the continuity and integrity of coal and makes it heterogeneity.3, 4, 5 Hol et al. 6 concluded that most micro-fractures developed parallel to the bedding fabric of the coal. Due to the cementing strength between the bedding and coal body being
