大型矿井井下巷道贯通测量方法及误差分析

Method and Error Analysis of Holing Through Survey of Underground Roadways in Large-scale Mines

结合具体工程实例,从平面测量与高程测量两角度,分析不同测量方法对巷道贯通精准度的影响,并通过对其误差的预计分析,检验了各测量方案的可行性,希望能为其它矿井相应技术的采用提供指导与借鉴。

Combined with specific engineering example,the paper analyzed the influence of different measuring methods on the precision of roadway holing through from the point of plane and elevation measurement,tested the feasibility of measuring scheme through prediction analysis of its error,which hoped to provide guidance and reference for other corresponding technology used in coal mines.
