Role Of Chemistry In Coal Mining
Coal mining played a supportive role as provider of energy to the growing gold mining industry and indeed, many collieries were historically and are today owned by gold mining companies. To these coal mine owners it was more important to keep the costs of their own energy inputs low, than to profit from coal mining itself4.

Role of microorganisms in reclamation of coal-mine spoils
Microbial communities play a crucial role in improving the soil fertility and productivity by breaking down organic matter into inorganic forms of mineralized nutrients accessible for plant uptake. During opencast mining, the mine spoils or overburdens created are often devoid of essential nutrients and have relatively lower water holding capacity.
