摘要
由于矿区长时间受风吹、日晒、雨水等自然现象的影响,造成表层矿体结构松散、强度降低,严重威胁工程测量工作的正常运行,为此提出工程测量中矿区变形监测作用方法的研究。以极坐标差分理论为监测依据,对矿区监测点的变形数据进行采集,根据观测值计算监测点的位移量,对监测点的斜距进行调整计算;通过实验论证得出,引入极坐标差分法的变形监测方法能够提高对矿区结构变形的准确预测,提高监测精度的29.68%。
Because of the influence of natural phenomena such as wind blowing, sunshine and rainwater for a long time, the structure of surface orebody is loose and its strength is reduced, which seriously threatens the normal operation of Engineering survey. Based on polar coordinate difference theory, the deformation data of monitoring points in mining area are collected,the displacement of monitoring points is calculated according to the observed values, and the slant distance of monitoring points is adjusted and calculated. To increase the monitoring accuracy by 29.68%.
