This work illustrates the proximate analysis on three types of coal samples obtained from Khushab mines in Pakistan. Analysis of the coal matrix was carried out to determine volatile matter, ash contents, moisture, fixed carbon contents, calorific values, and sulfur contents as per standards of American Society for Testing and Materials (ASTM). The results of proximate analysis show 30.46% fixed carbon content, 28.08% ash content, 6.96% total moisture content, and 34.5% volatile matter within sample A, whereas 40.56% volatile matter, 8.03% moisture content, 8.32% ash and 30.46% fixed carbon content was found in sample B. Sample C contained 15.44% volatile matter, 9.16% moisture content, 40.64% ash content, and 37.5% fixed carbon content, respectively. Sample B has higher calorific value and sulphur contents in comparison to A and C. These coal samples are of good quality from an industrial prospective, but they need to be desulphurized prior to industrial use for the sake of the environment.
