摘　　要：为探究高精度三维激光扫描技术在煤矿竖井井筒变形监测过程中的误差来源与控制方法,以龙煤鹤岗益新煤矿竖井井筒为研究对象,利用联系测量成果约束、基于靶球传递的竖井井筒变形监测扫描实验进行了误差控制方法研究和精度分析。结果表明:鉴于竖井井筒扫描时各测站观测条件的一致性较好,竖井井筒点位误差的主要影响因素为扫描视线俯仰角和扫描距离;随着测站间垂高的增加,累积中误差呈增加趋势,垂高为10、20、26 m时均符合限差要求;综合考虑精度、可靠性和经济等因素,确定最佳设站距离为20 m,最佳设站数为28站。由此得到了同等观测条件下,井深为400、600、800、1000 m竖井井筒的最佳扫描方案。This paper aims to explore the error source and control method of high-precision three-dimensional laser scanning technology used in the process of monitoring the deformation of coal mine shaft.The study taking the shaft of Longmei Hegang Yixin coal mine as the research object,the error control method and accuracy analysis are carried out by using the shaft deformation monitoring scanning experiment based on the constraint of measurement results and target ball transmission.The results show that,in view of good consistency of the observation conditions at each station during the shaft scanning,the elevation angle of the scanning line of sight and the scanning distance can be the main influencing factors of the shaft position error;with the increase of vertical height between stations,the cumulative mean square error shows an increasing trend,and the vertical height 10,20 and 26 m meets the tolerance requirements.Considering the factors of accuracy,reliability and economy,20 m is the optimal station setting distance and the optimal number of stations is 28.Thus,the best scanning scheme for the shaft with a depth of 400,600,800 and 1000 m under the same observation conditions is obtained.
