免棱镜全站仪观测井架倾斜度的方法

 利用免棱镜全站仪无协作目标测量功能，采集了井架上、下层监测点数据；并通过AutoCAD软件获取上、下层几何图形中心，根据两中心偏移量和两层之间的高度计算井架倾斜度。通过山东某煤矿主井井架的监测实例验证该方法的可行性；本实例中上、下层中心点位距离为73mm，高差为36.037m，倾斜度为0.002。实验证明该方法实施过程简单，观测效率优于传统方法。

Non-Prism Total Station Method to observe Inclination of Mine Shaft Headframe

Electronic total station without prism can measure the points with no synergic target. Based on this function, the authors collect the monitoring data of the upper and lower level. Besides, their geometry centers are obtained by Auto CAD. And then the authors calculate the headframe inclination based on the distance of the two centers and as well as the height between two levels. The authors put this method into practice of a coal mine in Shandong province, trying to prove its feasibility. The distance of the two centers is 73mm, the height is 36.037m and the angle of inclination is 0.002.According to the experiment, this method is more efficient in monitoring than the traditional one.
