During the year, we made major progress  in our dust suppression drive, with  benefits for the health of employees as  well as the underground environment.  We have invested in various initiatives  to reduce equipment noise, including,  for example, replacing underground  ventilation fans with quieter fans. We are  also working closely with other players  in the mining industry on initiatives to  further reduce noise levels. Sasol Mining operates according to clearly  defined environmental management  programmes, as well as internationally  recognised environmental management  systems based on the ISO 14001:2004  standard. In recent years, Sasol Mining  has made a substantial investment in a  mine water and brine treatment plant.  This plant continues to record solid  improvements in the volume of water  treated. In 2010, it treated 2 302  megalitres of water, up from 1 860  megalitres in the previous fi nancial year. Sasol Mining’s total coal production  increased to 42,6 Mt in 2010 from  39,1 Mt in 2009, as efforts to improve  output rates paid off with a 12% increase  in productivity. This can be attributed  to a focus on Operations Excellence and  by involving employees in these efforts.  We motivated staff to raise productivity  by introducing a revised bonus system,  allowing our miners to share in the  upside of increased production. The  sustained high output ensured that we  made up the strategic stocks depleted  during the unprotected strike of 2009.  The management-trade union partnership  forum introduced in 2009 has encouraged  constructive, open relations with  employees and has helped ensure a  stable production environment. * The recordable case rate (RCR) is a standard international measure for reporting work-related injuries and illnesses and other safety incidents resulting in injury.  The RCR is the number of fatalities, lost workday cases, restricted work cases, medical treatments beyond first-aid cases and accepted illnesses, for every 200 000  employee hours worked, reported on a 12-month moving average basis.
