| description |
The support in underground excavations is essential to preserve the life and health of the workers, damage to the equipment and to have proper progress of the excavation. The most common Rock support sets are the rock bolts, temporary or definitive. Among temporary rock bolts, there are the Split sets, widespread around the world due to their ease of installation and cheaper. Split Sets, have the appearance of a tube with a 15 mm slot in its entire length, manufacturers and suppliers recommended 38 mm diameter of drill holes and depths according to their length. In this research, the ground and holes were simulated with a special table and steel tubes. Split Sets, were conditioned to make anchors of 1, 2, 3, and 4 feet of bond length. Prepared the simulator tubes and Split Sets were installed, after which, were performed the pull test of the 3 samples for each bond length to determine their anchor capacity. Peak loads for each length researched were recorded in formats designed for this purpose. Compiling the recorded values and adjusting them according to certification of pressure gauge calibration carried out in UNI, obtained the anchor capacity for each of length tested. Results that have been captured in a table and graph, where is inferred that the anchor capacity of the Split Sets is affected by its bond length, and that do not have a relationship. Maximum bond length of anchorage tends to 4 feet, i.e., it is unnecessary to use greater lengths. |

Los elementos de sostenimiento de mayor aplicación son los pernos de roca, temporales o definitivos. Dentro de los pernos temporales, se tienen los Split Sets, muy difundido en el mundo por su facilidad de instalación y bajo costo. Los Split Sets, tienen el aspecto de un tubo con una ranura de 15 mm de ancho en toda su longitud, para cuya instalación los fabricantes y proveedores recomiendan taladros de 38 mm de diámetro y profundidades acorde con su longitud. Para realizar el presente estudio, se han simulado el terreno y los taladros con una mesa especial y tubos de acero, respectivamente. Los Split Sets, se acondicionaron para hacer anclajes de 1, 2, 3 y 4 pies de longitud efectiva de anclaje. Preparados los tubos simuladores y los Split Sets, se procedió con la instalación, luego del cual, se realizaron las pruebas de arranque de las 3 muestras por cada longitud ensayada para determinar la capacidad de anclaje. Las cargas pico para cada longitud en estudio, se registraron en formatos diseñados para este fin. Compilando los valores registrados y ajustándolos de acuerdo a la certificación de calibración del manómetro llevada a cabo en la UNI, se obtuvo las capacidades de anclaje para cada una de las longitudes ensayadas. Resultados que han sido plasmados en un cuadro y ábaco, de donde se colige que la capacidad de anclaje de los Split Sets es afectado por su longitud efectiva de anclaje, y que no guardan una relación. La longitud efectiva de anclaje máxima tiende a 4 pies, es decir, es innecesario usar longitudes superiores.Universidad Nacional Mayor de San Marcos, Facultad de Ingeniería Geológica, Minera, Metalúrgica y Geográfica2018-07-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/iigeo/article/view/1498610.15381/iigeo.v21i41.14986Revista del Instituto de investigación de la Facultad de minas, metalurgia y ciencias geográficas; Vol. 21 No. 41 (2018); 9-16Revista del Instituto de investigación de la Facultad de minas, metalurgia y ciencias geográficas; Vol. 21 Núm. 41 (2018); 9-161682-30871561-0888reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/iigeo/article/view/14986/13051Derechos de autor 2018 Emiliano Mauro Giraldo Paredezhttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/149862020-03-12T13:28:40Z |
