Abstract: As to the underground mining in metal mines, the lamella layer of polymer is a new type of area support, which is advanced, convenient, quick-acting and efficient. The support materials can provide huge consolidation strength for rocks in the process of control before and after yielding fracture, which has potential support in minerals and rocks. Through the experiments of uniaxial compression strength with and without spraying coating layer and the consolidation recovery effect test of wall-rocks with lamella layer, the potential support property of the polymer layer is inspected and demonstrated, and it provides a scientific argument for the new approach to resolve the problems in support of soft rocks tunnel.

Key words: Uniaxial compression strength, Support property, Lamella layer of polymer
