为解决弓长岭露天矿排岩场边坡不稳定对周边产生安全隐患问题.利用世界最高精度的测量机器人TM30,采用极坐标与测距三角高程测量方法来确定边坡的水平位移与垂直位移,并结合中国《工程测量规范》中对排岩场边坡变形观测等级与精度要求,对观测点点位及高程所能达到的精度进行了理论分析与论证.研究结果表明:采用TM30测量机器人对排岩场边坡进行水平位移与垂直位移测量时,如果将观测距离控制在500 m以内,并按二等9测回进行水平角、垂直角与距离观测来确定观测点的坐标与高程,可以满足排岩场边坡变形对观测点点位和高程精度的要求,并通过工程实际验证了其正确性.
In order to solve the potential safety problems in the periphery of the unstable rock slope in the open pit of Gongchang Mountain open pit, the world’s highest precision measurement robot TM30 is used to determine the horizontal displacement and vertical displacement of the slope , And combined with China’s “Engineering Survey Code” in the row of rock slope deformation observation grade and accuracy requirements, the observation point of the point and elevation can achieve the accuracy of theoretical analysis and demonstration.The results show that: the use of TM30 measurement robot pairs When horizontal and vertical displacements of row rock slope are measured, if the observation distance is controlled within 500 m and the horizontal angle, vertical angle and distance are measured by second-class 9, the coordinates and elevation of observation point can be determined It meets the requirement of slope position and height accuracy of the slope in the row rock field and verifies its correctness through engineering practice.
