Did you know?
WebRockburst risk is an increasing problem in underground mining worldwide, as the general trend is for mines to operate in deeper environments. In most mines affected by seismicity, the first line of defence to mitigate the potential consequences of rockburst is to install dynamic resistant ground support systems. WebJun 28, 2024 · In the last decade, a new polymer-based surface support material, thin spray-on liner (TSL), has started to take place of conventional surface support materials. TSL is defined as generally cement, latex, polymer-based and also reactive or non-reactive, multi-component materials applied to the rock surface with a layer of few millimeter thickness.
Web1.1. Development of Thin Spray-On Liners Thin spray-on liners (TSLs) are surface support materials that are sprayed onto the rock surface at a layer of 3 to 5 mm thickness [1]. TSLs (reactive or non-reactive) are generally cement, latex, and polymer-based. The first tests on TSLs were performed in Canada in the late 1980s.
