The influences of transport system of muck at daily excavation of Zagros Water Conveyance Tunnel (ZWCT) has been presented in this Research. To do this, the results of both rail transeport system and mechanized system of conveyor belt has been compared. The muck has been transported out tunnel at first 15.5 km length of (ZWCT). So, mechanized conveyor belt system has been replaced coincident with increase of tunnel length and rail system delays. Therefore, substitution of rail system of muck transport by conveyor belt has leaded to deacreas at time delays from 38.1% to 34.8% and increase of time percent of tunnel excavation from 13.8% to 35.5% because of excavation continuity.
