Abstract

Método de refuerzo de rocas, especialmente para reforzar estratos rocosos en minas de carbón en minas de carbón, que comprende perforar un orificio en el interior de una masa rocosa, introducir un elemento de refuerzo alargado dentro del orificio o barreno dejando un espacio entre el elemento y la pared del orificio, e inyectar un material fluido a base de lechada de cemento endurecible en el interior de dicho espacio, con lo cual, cuando se endurece el material de cementación , se adhiera el elemento a la pared del orificio o barreno y por consiguiente se refuerza la masa rocosa, caracterizado porque el elemento de refuerzo es un trozo de cuerda flexible.
