Abstract
Mine haulage drifts are the arteries of a mine. They are used for the transportation of blasted ore
from the draw point to nearby ore pass or dumping point in deep underground mines. Thus, they
must be remained functional during their service life. Otherwise, their instability could lead to
serious consequences such as injuries, delay of production and increased operational cost. The
objective of this paper is to evaluate the performance stability of mine haulage drifts with respect to
mining step adopting numerical modeling of analysis. A two-dimensional, elastoplastic, finite
difference code (FLAC 2D) is built for the purpose of this study. Haulage drift performance is
evaluated using stability indicators and numerical modeling results are presented in terms
displacement, stress and the extent of yield zones with espect to mining step.
