免棱镜全站仪的出现是矿山测量应用的重大里程碑。他是对传统经纬仪、全站仪的技术改进和重大创新。无棱镜测距精度高,反应速度快,具有激光指向仪的功能,在贯通测量中能够直观的指导生产。它的出现为井下控制测量、井下施工放样,贯通测量,危险的采空区测量带来了曙光,极大地提高了测量工作的外业作业效率和生命安全保障。 The emergence of prismless total station is a major milestone in the application of mine measurement. He is a traditional theodolite, total station technology improvements and major innovations. Non-prism Ranging high accuracy, fast response, with the function of laser pointing instrument, through the measurement can be an intuitive guide to production. Its appearance is the downhole control measurement, downhole construction stakeout, through measurement, dangerous gob area measurement has brought the dawn, which greatly improved the measurement of the field of homework efficiency and life safety and security.
