Title: Coal Mining 1 Coal Mining 2 Coal Mining. The goal of coal mining is to economically remove coal from the ground. Coal is valued for its energy content, and since the 1880s is widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In
associated with coal mining (Tiwary, 2000). In the Sydney Basin the common practice for coal mines is to dispose of wastewater to nearby streams and rivers (e.g. Wright, 2011). In NSW mine wastewater pollution is regulated by the Environmental Protection Agency (EPA) through ZEnvironmental Protection Licenses [ (EPLs).
