what two polluting effects come from coal mining

What Are the Benefits of Mining? - Research Summary

First of all, mining creates jobs. It is dangerous work and every year people suffer serious injuries in mining accidents. Some people even die. But demand for metals, crystals, coal, and other minable substances is only increasing. Another benefit of mining is that it spurs technological development.

Natural gas vs. Coal - a positive impact on the environment

With respect to carbon emissions, coal mining and the burning of coal account for a greater sum than any other fuel. Coal, unlike gas fuels and oil, does not emit carbons into the air in its natural state. However, during the mining of coal, methane is released into the air. Tremendous amounts of methane (CH 4) are released into the air in fact.
