sustainable value from Indonesian coal. In 2013, AI recorded a lost time injury frequency rate lTIFr
of 0.16 compared to 0.28 in 2012, better than our target of 0.25. We had 10 lost time injuries lTIs,
a 44 improvement from 18 lTIs in 2012. With a total of 62,060,850 work hours, we went 6.3 million
hours without a single accident. We had no lTIs in December 2013, an exemplary safety performance.
Coal Mining
2013 was our best year of production with 52.3Mt of thermal coal mined and hauled, an
11 increase. Strong customer demand, normal weather conditions and good performance by the
contractors combined to help attain our record results. our contractors performed at a high level,
with 145,680 tonnes mined daily on average from all three pits.
Tutupan remains our main mine, producing 38.65Mt in 2013, relatively lat year-on-year.
production from Wara was 7.87Mt in 2013, a 3 increase, while paringin grew by more than ive
previously, four contractors worked in the tutupan pit, while three contractors split the work in Wara
and paringin pits. Starting in 2013, we have two contractors working in tutupan, two contractors
in Wara and one contractor in paringin. this allowed for better co-ordination in each pit, thereby
improving productivity. We will also negotiate mining contracting rates to be more competitive
for 2014.
In addition to the new annual production record of 52.3Mt, AI and its contractors also achieved a
quarterly production record of 13.73Mt in 3Q13, as well as a daily coal-hauling record of 187,331 tonnes
in December 2013. the following table shows the breakdown of overburden removal, and coal
mining and hauling activities of our contractors as a percentage of the company’s total in 2013. Having a
number of contractors helps us obtain good results in terms of cost and performance.
Safety is always a top priority. Safe and reliable operations create trust with our partners, which
is important to achieve our objective of creating
