Gradual population growths, skyrocketing technological
developments and inter-State competitions increase the
energy demands continuously. Although the countries
try to diverse their energy sources in order to sustain
their developments, they also have to pay attention to
protect their energy independences. Thus, it is very
important to develop their self-resources. Coal is the most
common natural source which can meet our energy needs.
However, coal mine enterprises have to be administrated
cost-effectively in order get minimum energy costs.
In this study, the efficiency of Turkish coal enterprises
between the years 2003-2010 is measured by using Data
Envelopment Analysis (DEA). Then, indicators which
are the most important in estimating the efficiency were
determined by using the efficiency scores obtained by
DEA in the Data Mining technique.1
