Reference system transmission from surface to underground consists in transmitting in the underground the coordinates of a point and a guideline from which lifting is done in the underground network. Depending on the access roads, the reference system transmission into the underground is realized by several methods including transmission on a vertical shaft, transmitting on two vertical shafts, transmitting on coastal galleries or inclined plane. In case of transmitting the reference system from surface to the underground through a vertical shaft there are also known several methods and in this paper it is studied the mechanical transmission. Mechanical transmission of the reference system from surface to the underground consists in designing the wires in underground and determining their position of equilibrium respectively connecting surface and underground measurements. This paper proposes an analysis of accuracy index analysis of the measurements connection on surface and underground depending on which connection method you choose.
