Discussion of Error Estimating Plan in Second-Phase Project of Tongkuangyu Copper Mine

Zts Non-ferrous

Abstract

Multiple factors resulted in end-point error are discovered by analizing the causes for the wire end-point error.It is proposed firstly that the revolutionaxis equation can be used for conputation of end-point error in assigned tunnel direction.Based on actual conditions of second-phase project,a suggestion for error estimation and survey plan has been put forward.
