Abstract:
The use of pumpable polyester resin has become an increasingly popular choice for ground support in underground hard rock mining. Its ability to effectively reinforce and stabilise the surrounding rock mass with reduced quality control issues has turned it into a preferred product for rapid development in difficult ground and collapsing drill holes. One of the key advantages of pumpable polyester resin is its versatility. When used in a variety of ground conditions, including fractured rock, corrosive conditions, and high-stress environments, polyester resin injection is an ideal solution for many mining applications. Originally developed for use with hollow bar on mechanised bolters, pumpable polyester resin has evolved over the years with significant advancements in resin formulation, application equipment and installation techniques. Today, applying modern pumpable polyester resin remedies inefficient ground support processes. Efforts in the polyester resin systems development is increasing efficiency, designing applicable ground support, mitigating risk, reducing unplanned rehabilitation, improving quality control, limiting manual operator inputs, and integrating automated equipment and controls. This focus is making the application more consistent, which increases safety and productivity for the underground workforce. This paper will discuss the purpose of using polyester-type resin, new developments, quality control and efficiencies of the modern polyester resin system integrated onto rebar bolters, cable bolters and jumbo drills in the mining process.
