Abstract
The present invention discloses a real-time monitoring system and modeling method for the shape of goaf in mines, belonging to the field of mining goaf detection technology. The present invention includes a data acquisition module, a personnel positioning module, an information transmission module, and a data analysis module. A laser probe, a digital compass, and a tilt sensor are embedded in a miner's lamp, and then installed on a safety helmet; the data acquisition interval time is set, and the goaf is randomly scanned by underground workers at different positions or perspectives; then, the real coordinates of the scanning points in the goaf are calculated using the underground personnel positioning system and program, and data units and “conical” solid elements are established, and the constructed solid elements are gradually merged until the detection accuracy requirements for the goaf are met. The present invention is easy to operate, highly informationized, has small measurement errors, and with timely updated data. It can accurately monitor the shape changes of goaf during the mining process, quickly update the digital model of goaf, and provide data support for numerical analysis of goaf stability.
