Fuzzy-Controlled Tunnel Ventilation System

The working condition inside the tunnel under construction is badly affected by the occurrences of dust, CO and NOX due to the blasting, shotcreting and moving vehicles. Also, hot and humid conditions may be found at the excavation phase being caused from the machines and ground. The authors have developed a fuzzy-controlled ventilation system for improving the working conditions. The paper reports its validities based upon actual data and observations.
