The results indicated that the correction models exhibited strong performance across all levels of coal dust concentration (R 2 was, and RMSE was 8091μg/m 3). This study demonstrates that the application of lowcost sensors for personal coal dust exposure monitoring in underground coal mines is feasible with appropriate calibration.

Coal processing involves crushing, screening and beneficiation. Processing is where coal is converted from runofmine (ROM) coal to a product that meets the customer's requirements. Mined coal can include lumps. Crushing to a manageable size is required. Coal crushing can include a two stage process, dependent on deposit size.

Refined coal is the product of the coalupgrading technology that removes moisture and certain pollutants from lowerrank coals such as subbituminous and lignite (brown) coals, raising their calorific values. Coal refining or upgrading technologies are typically precombustion treatments and processes that alter the characteristics of coal before it is burned.
