预计结果的地表移动观测点选取

Observation points choosing of surface subsidence based on predicted results

地表移动和变形的观测工作一直都是研究开采沉陷危害的比较直接方式,而合理有效的观测站的设置就显得尤为重要。本文在布设观测站时,除考虑采深影响外,还利用概率积分法预计下沉曲线,根据下沉曲线上的特征点选取观测点。通过对某矿的实际应用表明该方法精度更高,具有一定的实际应用价值,从而为地表沉陷的观测工作提供了更好的方法。

Observation of ground movement and deformation has been the most direct way in researching mining subsidence,so the establishment of reasonable effective observation station appears especially important.When setting the observation station,in addition to considering the impact of mining depth,this article used probability integration method to estimate the subsidence curve.Then,according to the characteristic of the points on the subsidence curve,the author selected observation spots.Through the practical application in a mine it was showed that the method could offer more precise results,and has a certain practical value for surface subsidence observation.
