利用GPS+全站仪测量深谷铁矿洞口的实践

The Practice to Surveying Entrance of Iron Mine at Deep Valley Based on GPS and Total Station Instrument Technique

由于铁矿开采洞口隐藏于深谷一侧,加之森林茂密,铁矿物洞口位置的测绘带来了困难,导致利用GPS接收机或全站仪不能独立完成测量。这主要是GPS测量要求向上对天光学通视与全站仪测量平行光学通视要求限制其单独应用,因此,本文结合GPS和全站仪各自的优势,将两种仪器相结合,探索在高山深谷矿物洞口位置的测量方法,并对测量精度作出评估。实践表明,利用GPS+全站仪相结合的测量方法可以应用于高山深谷矿物洞口测量,并能够取得符合精度要求的测量成果。

The difficulty of surveying entrance of iron mine causes the project not to finish using GPS receiver or total station instru- ment alone. It is because its entrance lies in the side of deep valley and there are dense forests. Another reason is the requirements of upward visibility to GPS survey and parallel visibility to total station instrument. The article introduces the methods of surveying en- trance of iron mine and the surveyed accuracy using GPS receiver and total station instrument. They can make their respective advanta- ges complementary to each other. In the end the practice confirm the surveying method of using GPS receiver and total station instru- ment is also be concerned. In the mean time the method can acquire the result of demanded surveyed accuracy.
