"Coal seam" refers to a layer of coal that is found underground. It is like a natural deposit or reservoir of coal, which is a fossil fuel formed over millions of years from the remains of ancient plants. The
coal seam can be thick or thin, and it is usually found in between layers of rock or soil. It is where coal mining operations take place to extract coal from the ground.

The venture has been repeatedly delayed over several years amid changing state regulations for
coal seam gas and a lack of capital to move forward after the collapse in oil prices.
«This indicates that there are processes occurring — e.g. emissions
from coal seams during the drilling process — that are not captured in the inventory development process,» he said.
Coal companies are increasingly using this method because it allows for almost complete recovery
of coal seams while reducing the number of workers required to a fraction of what conventional methods require.

Mountaintop removal mining is one of the most environmentally destructive forms of coal extraction, where hills are flattened through the use of explosives to

Mountaintop removal is a radical form of coal mining in which up to 800 feet, sometimes more, of densely forested mountaintops are literally blown up to reach
thin coal seams.

He explained that an article I wrote in 2002 about fires, both natural and human caused, smoldering in
