地下采矿相似材料模拟试验观测方法探讨

A monitoring method of similar material simulation for underground mining

针对传统相似材料模拟试验测量角度法观测速度慢、数据处理复杂等缺点,文章利用高精度无棱镜全站仪测量特点,基于布尔莎七参数模型,构建了一种新的相似材料模拟试验观测方法:基于VC++6.0平台开发了观测数据后处理程序,实现了观测数据的自动化处理;通过将直接测量坐标法结果和传统经纬仪测量角度法结果对比分析,可知二者相差较小,证实了本研究所构建方法的可靠性;且测量速度较快,对于分析相似材料模拟试验的时空效应大有益处。

Aiming at the shortcomings of the traditional observation methods of similar material simulation as slow observation and complex data processing, combined with high-precision measurement of non-prism total station, based on Bursa seven-parameter model, a new observation method of similar material simulation was constructed in the paper. A post processor of observation data was developed with VC ＋ ＋ 6.0 to achieve the automated process of observational data. Through comparative analysis of the measurement results between the direct measurement coordinate method and theodolite angle method, it was showed that there was a small difference between them, which proved the reliability of the method presented in this study. Moreover, due to the rapid measurement, it would be beneficial to the analysis on the spatial and temporal effects of similar material simulation.
