摘　　要：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。For the first time in china,the block caving,an advanced and intensive mining systemwas introduced in a copper mine。One of the crucial factors important to its success is how tomonitor the surface subsidence caused by the system。The authors developed a computer-aid-ed stereo-photogrammetric method and the corresponding software to map the subsidencesurface and calculate the volume of the subsidence trough with satisfactory accuracy.On thebasis of comparing the subsidence volume with the ore output at successive time the autorshave worked out a new approach for analysing the caving condition in the rock-ore body andconcluded that the caving process in the mine was normal and no open space occured.Thedeveloped method and approach in this project are original both in China and abroad。
