我国首次在某铜矿采用的矿块崩落法是一种先进的高强度高效率采矿方法，但由于矿块崩落法引起地表下沉，所以如何监测，这对于该法能否成功地采用十分重要。作者研制了一种以计算机辅助地面立体摄影的测量方法，该法能通过自行设计的软件来计算陷落岩柱体积，能精确绘制塌陷区地形图；同时提出了一种分析岩矿体中崩落状态的方法，通过对比在连续时间内的放矿体积与陷落体积，得出了该矿陷落过程正常，不存在大的空洞的结论，这个项目的研究方法在国内外均为首创。
The first mining block caving method adopted by China for a copper mine is an advanced high-strength and high-efficiency mining method. However, due to the subsidence caused by the block caving method, how to monitor it is very important for its successful adoption . The author developed a computer-assisted terrestrial photogrammetry measurement method that can calculate the volume of the collapsed rock column through self-designed software and can accurately draw the topographic map of the subsidence area; at the same time, By comparing the volume and volume of ore draining in continuous time, the conclusion is obtained that the process of the ore subsidence is normal and there is no big hole. The research method of this project is the first in China and abroad.
