| Summary: | Effective ventilation conditions are one of the important factors in underground
mining operations to ensure worker safety and comfort. PT XYZ is a company
operating in the underground gold mining industry which requires optimization of
the local ventilation system. This research aims to analyze the effect of variations
in ventilation air pipe length on the efficiency of local ventilation systems using the
Computational Fluid Dynamics (CFD) method. Modeling was carried out with
ANSYS Fluent 2024 R2 Academic software to simulate air flow and temperature
distribution in the mine. There are 4 various models, model 1 (length duct to
minefront 15 m), model 2 (length duct to minefront 20 m), model 3 (length duct to
minefront 15 m), model 4 (length duct to minefront 15 m). The research results
show that a ventilation pipe with a length of 15 meters is able to provide optimal
fresh air supply and produce the lowest effective temperature, even though it does
not meet the standards set by the Ministry of Energy and Mineral Resources. This
research provides recommendations for more efficient air pipe design, including
consideration of outlet duct distance and gas and dust dilution, to improve the
safety and effectiveness of mine operations. |
