The paper reviews the development of resin—based reinforcement of rocks in British mines. The principles of reinforcement are outlined. Reinforcement units are assessed in terms of their component parts. Design characteristics are presented and discussed for a range of reinforcement units. The growth in the use of this form of reinforcement system is stated. The main applications are discussed and illustrated with actual examples. A new technique, developed in Britain, for improved roof control on coal faces with abnormal strata conditions, is described. The authors conclude with an appreciation of the scope for the future use of resin—based reinforcement of rooks.
