Abstract: This paper introduces key technologies and methods of comprehensive information automatic collection, wireless transmission，forewarning system in tunnel construction. Combining with modern telemetry technology, the system integrates sensor data acquisition (frequency, voltage, current simultaneously, digital etc.) of selected measuring section, three-dimensional laser scanning, advance geological forecast, blasting vibration monitoring and visualization monitoring. It can realize tunnel construction face image real-time display and analysis，certain tunnel construction monitoring data automatic collection and analysis, form the tunnel construction comprehensive information monitoring system, ensure tunnel construction safety in complex geological conditions of surrounding rock. The comprehensive, real-time and warning characteristics of TIS have an important practical meaning for dynamic design, construction management and improving the construction safety degree.

Key words: tunnel engineering, blasting excavation, comprehensive information, intelligent monitoring
