Mining is often the subject of a study of safety and health at work as one part of industry that carries the greatest risk of injury. The most of these analyses are directed on studying the method of injuries of workers and procedures that can prevent injury. Financial expenditures resulting from injuries of workers in Bogovina coalmine which occurred in 2016 are analyzed in this paper. Injury costs were processed based on the available data: compensations of the insurance companies to the injured workers, gross salaries of injured workers and similar. Within these data, the 'cost of one work day lost' (COWDL) is defined. Comparison of the COWDL, based on qualification structure of the injured worker and the severity of the injuries, was performed. Also, an impact analysis of expenditures related to indemnity related to injuries at work to mine operational costs were carried out.
