基于Knothe时间函数的煤矿区动态沉陷预计研究
Research on dynamic mining subsidence prediction based on Knothe time function
以某矿区的3212工作面为研究对象，采用基于Knothe时间函数的动态沉陷预计模型进行开采沉陷动态预计。计算了不同时间、不同位置的点的动态下沉值，分别与水准测量成果和D-InSAR监测结果进行了对比分析。实验表明，基于Knothe时间函数的动态沉陷预计模型所得到的结果符合开采沉陷导致的地表岩移规律；其结果与水准测量成果和D-InSAR监测结果吻合；最大误差不超过0.2米，能够满足动态预计的要求。最后提出了存在的问题和今后工作的方向。
dynamic mining subsidence prediction model based on Knothe time function was used to predict the dynamic subsidence with an example of 3212 working face. It calculated subsidence values in different areas and different time respectively and then compared with the leveling and D-InSAR achievements. It shows that the results we obtained using the model are anastomosed with the ground rock moving law. The results are consistent with the leveling and D-InSAR achievements, and the maximum error is less than 0.2 meter. It can meet the demand of dynamic mining subsidence prediction. At last, we discussed the problems existing and future work.
