coal - Students | Britannica Kids | Homework Help

Coal that is surface-mined is usually found in seams that range in size from 2 feet (0.6 meter) to more than 100 feet (30 meters) thick. Some seams contain as much as 200,000 tons of coal in a single acre (0.4 hectare). Normally, between 90 and 100 percent of this coal is recovered during surface mining operations.

Assessment of Mine Ventilation System Reliability Using Random ...

A mine ventilation system provides a fresh air flow to the underground workings in a coal mine. Such sufficient air volume can dilute and remove noxious gases (typically NOx, SO2, CH4, CO2 and CO) and maintain a suitable working environment for coal miners. On the other hand, a poor ventilation system often leads to serious consequences such as mine gas explosions, production loss or higher ...
