Abstract: The increasing length of permanent workings driven in unstable rock mass and in complicated mining and geological settings has resulted in increased labour intensity of rock support as well as higher consumption of metal used for their manufacturing. This article analyses types of support used for permanent mine workings. The interaction pattern between the grouting support and the surrounding the rock mass is described. Underground trials of the grouting support were performed using a reinforced hoseas lining to create inter-frame ties. As the result of this testing,a new rock support design was developed along with a way to further enhance its by using the reinforced hose. The new design secures a two-fold increase in the construction rates with the host rocks convergence reduced by 1.8–2.4 times and the rock support bearing capacity increased by 2.5–4.0 times. The proposed technology provides backfilling of the space behind the rock support; reduces the labour intensity of rock support; increases the face advance; provides rapid support of rocks and backfilling of cavities behind the rock support; eliminates leakages of the cement slurry; mechanizes the set blocking process; prevents doming which eliminates the need for subsequent shotcreting of the supported opening.
