The invention discloses a ventilation self-
adaptive control system and method for high-altitude
tunnel construction, and the
system comprises a
mobile device and monitoring subsystem which is used for arranging a monitoring device capable of moving along with tunneling of a tunnel, and collecting dust concentration, CO concentration, air pressure, temperature and
humidity data and mileage positions of measuring points; the ventilation working condition acquisition subsystem is used for acquiring the ventilation working condition to determine the ventilation flow; the
data processing and source item inversion module is used for constructing a one-dimensional
convection-dispersion discrete model of the segmented control body based on the
monitoring data and inverting the time-varying release rate and the total yield of blasting pollutants; the ventilation self-
adaptive control module is used for generating a staged ventilation strategy according to the inversion result; and the
user interface and alarm module is used for displaying real-
time data and a ventilation strategy and triggering an alarm when the real-
time data and the ventilation strategy exceed the standard. According to the method, the blasting
pollutant source item can be accurately inversed in real time, and the optimal ventilation strategy is dynamically generated according to the blasting
pollutant source item, so that ventilation efficiency maximization and
energy consumption minimization are realized, and construction safety is guaranteed.
