                         (Monitor e Imageador de RAios-X) experiment for Gamma-Ray Bursts 
                         (GRBs). MIRAX is an X-ray astronomy mission designed to perform a 
                         wide band hard X-ray (10-200 keV) survey of the sky, especially in 
                         the Galactic plane. With a total detection area of 169 cm2, large 
                         field of view (FoV, 20°×20°), angular resolution of 1°45' and good 
                         spectral and time resolution (~8% at 60 keV, 10 \μs), MIRAX 
                         will be optimized for the detection and study of transient 
                         sources, such as accreting neutron stars (NS), black holes (BH), 
                         Active Galactic Nuclei (AGNs), and both short and long GRBs. This 
                         is especially important because MIRAX is expected to operate in an 
                         epoch when probably no other hard X-ray wide-field imager will be 
                         active. We have performed detailed simulations of MIRAX GRB 
                         observations using the GEANT4 package, including the background 
                         spectrum and images of GRB sources in order to provide accurate 
                         predictions of the sensitivity for the expected GRB rate to be 
                         observed. MIRAX will be capable of detecting ~44 GRBs per year up 
                         to redshifts of ~4.5. The MIRAX mission will be able to contribute 
                         significantly to GRB science by detecting a large number of GRBs 
                         per year with wide band spectral response. The observations will 
                         contribute mainly to the part of GRB spectra where a thermal 
                         emission is predicted by the Fireball model. We also discuss the 
                         possibility of detecting GRB afterglows in the X-ray band with
