Research and application of multi-source information detection technology for drilling rescue of mine

Drilling rescue of mine is a new type of rescue technology. In order to quickly and accurately obtain the information on drilling channel, the location distance of the trapped person and the characteristics of the gas environment in the disaster area during rescue, as well as to realize the two-way video and audio communication between the trapped person underground and the rescue commander on the ground, theoretical research and technical development were conducted with the technical methods such as multi-source information fusion, dual-stream network video service, edge computing, intrinsically-safe circuit control, and ultra-wideband radar. Meanwhile, two key technologies were proposed: a real-time collection and transmission technology of various sensor data in disaster areas and a hidden-space life information detection technology. Specifically, the former could realize the real-time detection and presentation of multi-source information in the process of drilling rescue, while the latter could realize the detection and positioning of personnel life information behind the obstacles. Then, the trial production of prototype and the field tests were carried out on this basis, and thus a series of multi-source information detection equipment for drilling rescue of mine was developed, including the portable intrinsically-safe power supply with large capacity, the ultra-wideband radar detection system (capable of detecting the life behind the obstacles), and the multi-source information (the parameters of video, audio, temperature and gas environment) detection system for drilling rescue. This set of equipment was used in the accident rescue of Shandong Pingyi Gypsum Mine and Shandong Hushan Gold Mine, with the trapped person and the information on drilling channel and underground environment detected successfully. In the rescue of Xinjiang Fengyuan Mine accident, the underground water and gas environment was monitored in real time to avoid the secondary casualties of rescuers. The system comprises a borehole detector for diving, video and audio environment monitoring, a twisted pair-based borehole communication line wheel, and a system monitoring terminal. The development and application of the results could provide some equipment support and technical reference for multi-source information detection in long-distance boreholes.
