Abstract
The demand of limestone and clay as raw materials of
cements has to be filled so that the cement production
processing becomes streamlined. Into fills the limestone and
clay demands, it needed mine processing.
The mine processing is done in two places, that are
limestone and clay mining and the main mining tools that
used are dump truck and excavator. The main mining tools
determination is hard to be defined by using analytic. because
the high variability of demand of limestone and clay, distance
of material movement, and also the probability of crusher’s
operations.
Based on the problem above, it needed to do next
research to determine the numbers and combinations of dump
trucks and excavators that used to fill the monthly demand of
limestone and clay in a year. The method that can be used to
solve the problem is simulation.
Simulation can imitate the real mine system so that it
can develop the scenarios to do experiment to find the
numbers and combinations of dump trucks and excavators.
The best combination is the combination that can fill the
demand and creates the lowest total cost.
Based on the result of simulation, the best scenario is
third scenario. Because it creates the combinations that can

fill the demand and creates the lower total cost than the other
scenario. The suggested scenario is operating the crusher
fully in a year so that the numbers of dump trucks and
excavators that needed to fill the demand becomes fewer and
effective for PT. UTSG.
Key words: limestone and clay mining, variabilities of
system, simulation model, and concept of cost.
