The increase in the number of incidents in 2014 is mainly due to the increased awareness of personnel (machinery operators -
technicians) of the need to report such incidents, combined with the simultaneous decrease in the number of unreported
incidents. These incidents are an unavoidable part of the mining process, as they are caused primarily by wear and tear of
lubricant pipes and by damages to machinery by falling rocks. They do not involve serious spills and are dealt with immediately
by carefully collecting the quantity of contaminated soil and forwarding it to the hazardous waste area for appropriate
handling.
