Abstract: Development of Real-time AE monitoring system is based on practice of long-term AE monitoring goafs in small underground mines of eastern Hubei.The low cost instrument has such function: managing the system via IE interface, collecting AE signals in real time and removing manual fake data input with ROM data storage.The system is composed of a WUST AE instrument and a platform of data collection and analysis.Data can be transmitted not only through the network of XBEE wireless and wire direction connection but also manual carry to a host computer.Data analysis of the platform may predict stability of goafs.Managers can log in the system via a web browser and make a timely response to abnormal situations of goafs.

Key words: Goaf, Acoustic Emission, Real-time Monitoring, Mine Safety, Management System
