REAL-TIME MINE GOAF MORPHOLOGY MONITORING SYSTEM, AND MODELING METHOD

A real-time mine goaf morphology monitoring system, and a modeling method, which belong to the technical field of mine goaf detection. The system comprises a data collection module, a person positioning module, an information transmission module and a data analysis module. Laser probes (21), a digital compass (24) and an inclination sensor (25) are built in a mine lamp and then the mine lamp is mounted on a safety helmet (1); a data collection interval time is set; a goaf is randomly scanned by means of the laser probes (21) by a downhole operator at different positions or different visual angles; then, the real coordinates of goaf scanning points are calculated by means of a downhole person positioning system and a program, and data units and "conical" entity units are established; and the union set of the established entity units is progressively solved until the requirement of goaf detection precision is met. The system is simply and conveniently operated, has a high informatization degree and small measur
