The invention discloses an underground-cavern-group-construction-schedule simulating optimization method based on ventilation numerical simulation. The underground-cavern-group-construction-schedule simulating optimization method includes the following steps that (1) ventilation numerical simulation and the underground-cavern-group construction schedule are combined, and an underground-cavern-group-construction-schedule simulating optimization mathematical model based on ventilation numerical simulation is established; (2) an underground-cavern-group-construction-ventilation two-phase-flow hybrid simulation theoretical method is provided; (3) an underground-cavern-group-construction-ventilation numerical simulation parameter base is established; (4) an underground-cavern-group-construction-ventilation three-dimensional fine physical model is established, and grids are divided; (5) underground-cavern-group-construction-ventilation two-phase-flow hybrid simulation under different excavation schedules is achieved; (6) simulating optimization analysis of underground-cavern-group-construction whole process is carried out in cooperation with the ventilation numerical simulation result. According to the underground-cavern-group-construction-schedule simulating optimization method based on ventilation numerical simulation, the whole wind flow structure, pollutant space distribution and the dynamic variation rule in cavern groups are solved, and wind-flow-field transient pulsation information and the dust particle dispersion mechanism of ventilation difficulty areas can also be obtained.
