Comparación de métodos de mapeos topográfico subterráneo de la mina artesanal La Zamorana, ubicada en el cantón Paquisha, provincia de Zamora Chinchipe

Abstract

This thesis aimed to compare different types of underground topographic maps in the artisanal mine ‘La Zamorana’, which belongs to the concession company “SOCIEDAD DE HECHO MINERO LA ZAMORANA”, located in Zamora Chinchipe province, specifically in Paquisha canton. Several methods of underground topographic mapping were conducted through various measuring instruments such as a total station, mobile LiDAR sensor, tape and compass due to select the best method that suits the needs of the company. Data recorded in software such as Excel, AutoCAD and CloudCompare were processed to achieve 3D modeling and determine the shape of the main access gallery to the mine. The coordinates obtained were used for an accurate estimate by applying different equations such as Euclidean distance, Absolute Error, scattering diagrams and correlation coefficients. The data obtained from the topographic survey with total station was used as a reference sample of reality. The cost per meter of work was determined for each of the topographic surveys carried out, with the aim that the company involved can choose the mapping method that best suits its need. Moreover, data acquisition and processing speed calculations were also performed to determine which mapping method is faster to execute.
