矿井三维地质编录系统在煤矿巷道编录的应用

Application of Mine 3D geological cataloging system in coal mine roadway cataloging

随着采煤智能化水平的不断提高,要求矿井地质编录工作朝着细、准、快的方向发展。以近景摄影测量理论为基础,开发了矿井地质三维编录系统,相较于传统的地质编录工作,实现了巷道实景三维建模,影像成图精度高、三维效果逼真。该系统在杜儿坪矿掘进巷道进行了应用,应用表明,该系统提升了地质信息资料的数字化、精确化、自动化、出图标准化,在保证简单操作的前提下,减人提效,将井下场景搬到井上处理,留存实景三维模型,便于后续对现场地质情况的再次分析,并进一步提升地质编录测量精度。

With the continuous improvement of the intelligent level of coal mining, the mine geological cataloging work is required to develop in the direction of fine, accuracy and speed. Based on the theory of close-range photogrammetry, a three-dimensional cataloging system of mine geology has been developed. Compared with the traditional geological cataloging work, the 3D modeling of the roadway is realized, and the image mapping accuracy is high and the 3D effect is realistic. The system has been applied in the heading roadway of Duerping Mine. The application shows that the system has improved the digitization, accuracy, automation and standardization of geological information data. On the premise of ensuring simple operation, it can reduce the number of people and improve efficiency, and move the underground scene. Go to the well for processing, and save the 3D model of the real scene, which is convenient for subsequent re-analysis of the on-site geological conditions, and further improves the accuracy of geological cataloging and measurement.
