Recently, a key R&D project led by Shendong Coal, in collaboration with multiple research institutes and universities, made major progress. Two sets of core detection equipment prototypes were successfully developed and put into application, with supporting data analysis software launched simultaneously. The progress marks a technological breakthrough in coal mine water hazard prevention and underground transparent geological construction.
Underground aquifers in coal mines are hidden and complex. Traditional detection methods face common industrial challenges, including narrow detection coverage, low data accuracy, delayed warning and low operating efficiency. Such defects easily trigger water inrush risks and restrict safe and high-efficiency mining for a long time. In response, the project team developed new intelligent detection equipment and planned to launch five sets of specialized equipment with fully independent intellectual property rights. At present, two core prototypes for seismoelectric combined monitoring and borehole-roadway transient electromagnetic detection have been development. The project team has obtained five invention patents and two software copyrights, and released three high-level academic papers in Peking University core journals and SCI/EI indexed publications.
The new technologies offer prominent practical merits. They accurately identify water bodies and complex geological structures 120 meters ahead of roadways and 50 meters in surrounding areas, with the early warning accuracy for water hazards exceeding 90 percent. The technologies enable intelligent detection along tunneling operations. Full-area scanning can be completed within three minutes, with a signal recognition accuracy rate reaching 95 percent.
The deployment of equipment prototypes marks the project’s official shift from theoretical research to on-site verification and application. Project achievements will be fully promoted and applied across Shendong mining areas, providing key support for coal mining operations with fewer personnel, more intelligence and enhanced safety, and empowering green transition and high-quality and sustainable development of the mining areas.
