Abstract Through the measurement of underground mining engineering measurement, Tunnel engineering survey, the project investment is large, so through high quality requirements become an important link. In order to ensure the work through measuring a reasonable through measurement programme, To meet the requirements of production design, not only for low accuracy loss caused by engineering, Can not blindly pursue high precision and increase the workload, the waste of manpower and material resources. So the development through the measurement scheme, Must be error prediction, Select the optimal penetration plan.
In this paper, through large tunnel engineering based on, According to the design of Surveying and mapping instruments existing at least three through scheme, To determine the various parameters according to the error measuring method and instrument, Then the error prediction. According to the expected error, determined to meet the requirements of the project through the project, In precision, The size of the workload, The difficulty of the job, Considering the economic determine an optimal scheme through.
Keywords: Roadway expedite, Error is expected to plan, through optimization.
