Coal Mining. Health effects from coal mining include: the release of methane (CH 4), a potent greenhouse gas estimated to account for 18% of the overall global warming effect triggered by human activities (CO 2 is estimated to contribute 50%).; the release of carbon monoxide (CO) from explosives, which pollutes the air and poses a health risk for mine workers.
The strength and elastic module of the coal seam influence the fracture mechanics of an outburst. Stored elastic strain energy is released, and the failure is usually brittle indicating that the strain energy is not being used to distort the strata and a large proportion is still stored at the moment of breakage.
