Abstract:

HaLam is one of the underground mines in which mine structure is with vertical opening shaft. Therefore, the use of gyro-theodolite has been widely applied in Vietnam for determining the azimuth for baseline of underground control network. The accuracy estimation for underground control stations is an important step for the establishment of control networks. The paper presents the method and results of using gyro-theodolite for the measuring azimuth baselines of underground control network in Vietnam and specification for HaLam underground mines.
