青海多拉隆哇金矿区测量控制网的建立

The Establishment of a Survey and Controlling Network in Duolalongwa Gold Mining Area,Qinghai Province

针对青藏高原海拔高、冰冻期长及气压低等自然环境恶劣的实际情况,指出在青藏高原金矿勘查工作中进行等级控制测量易产生的问题,提出降低地球曲率、大气折光、气压、温度及高程等因素影响测量控制网布设效率和精度的具体措施。以青海省门源县多拉隆哇矿区为例,提出用全站仪建立矿区基本控制点,实践证明,在青藏高原植被稀少、通视条件较好的的山区该仪器具有测量速度快、精度高的特点。

Aimed at the actual conditions for Qinghai-Tibet Plateau：high altitude, temperature varied,long frozen period squall, lightning, heavy rain, snowfall vagaries of thin air, lack of oxygen, strong ultraviolet radiation ,low air pressure,we have identified some easy happened problems in the gold mine commissioning workslevel control measurement in Tibetan Plateau area.An example of Qinghai Province Duola Long wow minenetwork is offered,we point out that using Total Station establish mine basic control points.It is so fast, and has a high precision in the mountains in the Qinghai-Tibet Plateau which have sparse vegetation and good intervisibility.Those targeted methods and measures provide important references for the work of level control measurement.
