Computer Simulation Of The Mining Operations In Opencast Lignite Mines Operating Bwes, Conveyors And Stackers

SIMPTOL, a computer simulation program written in FORTRAN IV for use with Cyber 171/8 System at the National Technical University of Athens, describes the mining operations in an opencast lignite mine operating Bucket Wheel Excavators, Conveyors and Stackers. The central objective of the program is to aid management in the selection of a BWE-Conveyor-Stacker System for a given lignite deposit and equipment layout. Much information can be gained from the program with proper manipulation of the input data, which refer to mining profile, soil characteristics, equipment specifications and availabilities and time study data. The other objective of the program is to aid production scheduling in terms of forecasting production rates of the system. The program has been applied to Kardia lignite mine to evaluate its usefulness to represent the actual situation of the system being simulated.
