SPECIAL TOPOGRAPHIC WORKS IN THE RAMP OF A VERTICAL SHAFT
Abstract
The accuracy of transference from the underground surface of the topographic reference system is determined by the mining work on topographic transmission papers. If mining is vertical, topographic operations are complex and require permanent preoccupation for improvement. The paper meets this requirement, presenting possibilities for improvement of junction methods (surface, underground) of topographic elements used for mechanical transmission. The mechanical method of transmitting the underground surface reference system requires topographical operations on the junction of surface topographical elements, the junction of topographic elements in the underground and the determination of the equilibrium positions of the metallic wires. The reference system linking topographical topographic work to underground topographic work is determined by the elements that materialize it. the reference system is materialized as is known by the coordinates of a topographic point and the direction of a direction. It is important to know that the topographical elements that make up the surface reference system are closely related to their methods of determination, so that the points materialized near the mining work are points obtained by developing the geodetic network.
