Abstract
El contenido de esta investigación tuvo como tema principal la estandarización
entre cuadros de madera mediante un estudio geomecánico en la mina Barro Negro -
Sayapullo.
El Proyecto es aplicada y de enfoque cuantitativo, y se centró en realizar un
estudio de geomecánica, para saber el comportamiento de la roca, mediante el RMR -
Bieniaswki, Q de Barton y Índice Geológico, para optimizar cuadros de madera, los
cuales contaban con un diámetro de 8 pulgadas, la altura de hastiales de 1.8 m y un
sombrero de 2 metros, en la mina se colocan cuadros cada 60 - 80 cm en los primeros
recorridos, entonces se hicieron pruebas en 40 estaciones en dicha mina, que es cuprífera,
perteneciente a la empresa Corporación Yin’s Perú Inversiones, en donde se hicieron las
pruebas en las labores por celdas geomecánicas, para conocer el distanciamiento
adecuado. Como resultado, los valores RMR - Bieniaswki son 50 - 70, que es una roca
regular a buena, Q de Barton valores entre 15 - 35, como roca buena, y el método GSI la
calidad es LF/B (Levemente fracturada, buena) - LF/R (Levemente fracturada, resistente).
concluyendo que la separación entre cuadros es 1.5 a 1.6 mts por el tipo de roca,
cada cuadro cuesta S/500 (Materiales y mano de obra), con un gasto para los 130 primeros
metros de S/85000.00, al cambiar la separación entre cuadros, el costo seria S/42000.00,
que significa una reducción de costos al optimizar el uso de cuadros de madera en la mina
Barro Negro
The content of this research had as its main topic the standardization between wooden frames through a geomechanical study in the Barro Negro - Sayapullo mine. The Project is applied and quantitative in focus, and focused on carrying out a geomechanics study, to know the behavior of the rock, using the RMR - Bieniaswki, Barton's Q and Geological Index, to optimize wooden frames, which had a diameter of 8 inches, the height of the gables of 1.8 m and a cap of 2 meters. In the mine, squares are placed every 60 - 80 cm in the first tours, then tests were carried out in 40 stations in said mine, which is a copper mine, belonging to the company Corporación Yin's Perú Inversiones, where tests were carried out in the work by geomechanical cells, to know the appropriate distancing. As a result, the RMR - Bieniaswki values are 50 - 70, which is a fair to good rock, Barton's Q values between 15 - 35, as a good rock, and the GSI method quality is LF/B (Slightly fractured, good) - LF/R (Slightly fractured, resistant). concluding that the separation between squares is 1.5 to 1.6 meters due to the type of rock, each square costs S/500 (Materials and labor), with an expense for the first 130 meters of S/85000.00, when changing the separation between squares, the cost would be S/42000.00, which means a cost reduction by optimizing the use of wooden frames in the Barro Negro mine.
