Abstract
In unfavorable strata conditions, it is often necessary to install additional long tendon support as part of a primary support cycle. Although these support systems provide the required additional stability to the roadway, installation does have a significant effect on the rates of development. To overcome the slow cure time of Portland cement type grouts, the use of two component resin systems such as Polyurethanes and Urea Silicates have become favored but concerns over creep properties has led to the development of a new two component grouting medium which displays the properties of traditional cable grouting materials with the rapid reaction times of pumpable resin systems. This paper describes product testing, product application - surface trials, underground trials and full-scale applications of the Tekthix system in a dynamic underground environment.
