Caracterización de rocas desde el punto de vista de su abrasividad “un estudio de caso” diseño prototipo máquina para determinación del DRI (índice de la tasa de perforabilidad)

Abstract

This work shows the results of tests such as (Simple Comprehension, Tensile Strength, Punctual Load, Method to determine the bounce number (Schmidt Hammer), Ultrasound Speed, Schimazek Index and Abrasivity Index Cerchar Method CAI), made to specimens of rocks of the Guadalupe Group, as a case study, and in order to determine their abrasiveness against wear and tear of drilling and cutting tools. It also establishes the existing relationships with results under the parameters of their physical-mechanical properties, as well as their mineralogical typologies, through Binocular Stereoscopic Magnifying Glass, Stemi Brand 305, later in the laboratory of the GMAS SAS company, thin sections are made of each of them, for its petrographic characterization, in the research laboratory of the Santo Tomás University, and under the petrographic microscope, CarlZeissGmbH brand, Axion Scope-A1. Made by the geologist of the National University of Colombia and professor at the University of Santo Tomás de Aquino María Victoria Mejía Ramírez.

As the central axis of the investigation, the Abrasivity Index of the selected material is determined and correlated with the other tests carried out on these materials; with the mineralogical and petrographic characterization of the samples, it is characterized according to its shape, size, selection and degree of sphericity of the grain of the material.

The research reveals the prototype design of the equipment for the determination of the DRI (drivability rate index), a prototype that is proposed as the final product of this research work and whose construction is recommended, as Contribution to future research on the abrasiveness of rock massifs.
