Recently, the scientific and technological achievements of “empty area (field) three-dimensional exploration and visualization technology†jointly developed by the Zhongfan University's Nanfankou Lead-zinc Mine and Central South University passed the review and appraisal organized by Shaoguan Science and Technology Bureau, marking the acquisition of this technology. Breakthrough progress.
The goaf formed by underground mining of mineral resources is one of the main sources of disasters that endanger the safety of mine production. It has the characteristics of complex space, dynamic change of space status and stability, and large damage. At present, China adopts the traditional method of detecting empty areas (fields). The acquisition of information on the empty areas emphasizes interpretation. It can only roughly determine the existence and location of empty areas, and is affected by the downhole environment, especially for the processing and interpretation of detection information. There are obvious weaknesses that seriously affect the accuracy of open space detection.
It is reported that since the joint research group of Zhongjinling South Fankou Lead-Zinc Mine and Central South University was established in 2010, it has successfully broken through the lack of information acquisition capability of traditional open space (field) detection technology through nearly four years of independent research and development and scientific and technological research. Can not achieve the three-dimensional space (field) spatial information detection and other technical bottlenecks, and creatively solved the three-dimensional accurate detection and visual expression, calculation, management, analysis and other issues of the underground metal and non-metal mine goaf (field). At present, the technology has reached the international advanced level, has a high degree of engineering versatility and practicality, social and economic benefits significantly. (Zhang Hui / Ma Yi)
