Mining and processing copper and minerals involves working with large, heavy equipment, explosives and hazardous chemicals – often underground and sometimes at extreme temperatures. Our employees also experience common workplace hazards from driving vehicles, working at heights and operating machinery.
We believe it is challenging but entirely possible to prevent accidents, as long as the right approach and management systems are in place and sufficient equipment and training provided. Our long-term ambition is to provide a safe workplace free from injuries and illness, though we acknowledge that this will require considerable management focus and investment.
Fatalities
We deeply regret that 15 employees lost their lives in 14 separate incidents at Group operations in 2009, a rate of 2.4 fatalities per 10,000 direct employees. Thirteen of these were in the Copper Division, one in the Power Division, and one in the Gold. Two contractors in our Power Division also sadly died. We will report contractor fatalities across the Group in the 2010 Annual Report.
Rock falls were the most common cause and led to eight deaths. See the case study below for examples of our efforts to reduce this kind of incident. Four fatalities involved moving machinery. There was a substantial reduction in falls from height, the primary cause of fatalities in 2008.
Committed to responsibility
Preventing rock fall
Our operations are introducing new technologies to prevent rock falls and roof collapses – the most common cause of fatalities in our operations.
For example, we have been working with mining engineers Minova CarboTech on ways to strengthen rock. Our Artemyevsky and Orlovsky mines are testing Minova’s roof-bolting systems for tunnelling, as well as sealants and resins for filling cavities and backfilling behind arch supports. The rock surrounding both mines is unstable, increasing the risk of roof falls after blasting or down-time. We usually backfill the dome folds resulting from these rock falls with materials such as concrete and timber, but roof collapses can still occur. In 2009, this led us to suspend some operations for over two months, but work resumed after backfilling with Minova’s Carbofill phenolic resin foam, reinforced by metal arch supports. One square metre of this solidifying foam can support up to 12 tonnes of rock, substantially reducing the risk of rock falls and roof collapse.
In 2009, we installed a seismic monitoring system at our Zhomart mine to identify changes in the stress-state of the rock, caused by mining. We have used a similar system at Zhezkazgan since 2007, where it has forecast all subsequent rock falls and collapses of any significance. The Zhomart mine’s system can record even small fractures induced by mining. The underground and surface sensors record around 60 signals a day, which we use to identify the coordinates of fractures and assess changes in the rock. This allows us to determine trends in the spread of rock fractures and predict problems before safety is compromised. We plan to install seismic monitoring at mines in other regions, starting in 2010 at our Orlovsky mine in the East Region, which is particularly prone to rock bursts.
While every death is a tragic loss, there has been a 53% decrease in the number of fatalities since 2008. Our operations investigated every fatal incident and serious incident and reported their findings to the Group HSE Committee and, where appropriate, to the Fatal Accident and Serious Incident Review Panel. Our fatality and serious incident investigation reports comprise a full description of the incident including photographs and sketches, plus an analysis of the work area, procedures followed and protective equipment used. This information is used to identify the root cause of the incident and preventative measures for the future. The reports are sent to the divisional Chief Executives and HSE committee chairman within 48 hours of completing the investigation.
We attribute the reduction in fatalities to improved production controls, a greater emphasis on management responsibility and an increase in the number of site inspections. We carried out 2,759 site inspections in 2009 and stopped operations on 830 occasions as a result of the safety violations found. We carried out disciplinary proceedings with 1,975 employees in relation to these violations, and 49 employees lost their jobs. We recognise that serious injuries and fatalities can cause both emotional and financial difficulties to employees and their families, and we provide financial support to the families of the victims of fatal accidents.
