摘要
相似模型试验经常被用于模拟煤矿地表沉陷规律研究,为了提高模型试验中的位移监测精度,以开滦集团钱家营矿12-1深部开采工作面为蓝本建立相似材料模型试验,将航空摄影测量中航带思想应用于相似材料模型试验,设计了模型试验条带式的监测流程。利用罗德里格矩阵的坐标转换参数解算的模式和步骤,将不同条带的模型测量数据转换到同一测量坐标系下。试验研究表明,针对模型试验中的位移监测,条带式摄影测量减小了测量误差,罗德里格矩阵提高了坐标转换精度。
Similar model tests are often used to simulate the surface subsidence law of coal mines. In order to improve the accuracy of displacement monitoring, the air strip idea of aeronautical photogrammetry was applied to similar material model test basing upon deep 12-1 working face in Qianjiaying Coal Mine, the authors designed experimental procedures with strip style, used pattern and step of coordinate conversion parameter calculation of Rodrigo matrix and switched data of different air strip model measurements to the same measuring coordinate system. The results showed that the strip type photogrammetry reduced the measurement error for the displacement monitoring in the model test, and the Rodrigo matrix improved the accuracy of coordinate transformation.
