Jharkhand, a state in India is rich in minerals particularly coal. Large number of mines is excavated here. Opening of new mines and expanding existing mines causes air pollution. The main pollutants emitted are suspended particulate matter, oxides of nitrogen, sulphur dioxide and carbon dioxide. In this paper empirical models are developed to calculate SPM concentration in terms of NOx concentrations and SO2 concentrations. It has been seen that there is a good linear relationship between hourly SPM and NOx concentrations and also between SPM and SO2 concentrations.
