二矿470水平南翼主运皮带巷贯通测量设计方案的研究

Study on the Design Scheme of Transfixion Measurement of the Main Belt Roadway of 470 Horizontal South Wing of No.2 Mine

本文主要是对阳煤集团二矿470水平南翼主运皮带巷贯通工程进行测量方案设计,从井下导线测量、井下高程测量和贯通误差预计等方面进行了分析。实践结果表明,该贯通测量方案以较高的精度顺利实现了巷道的相向贯通。

This paper mainly designed the survey scheme of the main belt tunnel project of470horizontal south wing of the No.2Mine of Yangquan Coal Group,and analyzed the underground traverse survey,underground elevation survey and transfixion error estimate.The practical results show that the tunneling scheme achieves the phase tunneling successfully with high precision.
