Most standard ground support schemes are not able, or only have a limited capacity to cope with dynamic loading caused by rockbursts. High-tensile steel wire mesh has proven its performance and suitability for the application as rockburst support or support for high-deformable ground during static and dynamic tests at the Western Australian School of Mines (WASM) in Kalgoorlie, Australia. Due to the high- tensile wire strength and ability for high deformation of the high-tensile mesh, this ground support system can be used in high stressed environments. An automated roll mesh handler was developed and successfully tested in Australia for the application of high-tensile chain-link mesh in underground support. The handler is compatible with all standard multi- boom jumbo drilling equipment. The mesh handler comprises a cassette system holding the mesh roll mounted on one of the booms and the drilling/bolting element is mounted on the other boom. This allows the application and pinning of the high-tensile mesh simultaneously. The innovation reduces manual handling and personnel exposure in the installation process, reduces support cycle time (initial trials suggest a quicker installation time over current sheet mesh methods), improves the quality as the high-tensile mesh conforms more closely to the rock surface. This reduces unravelling of material in the voids and bagging of the mesh. There is no need for personnel to enter unsupported ground as the jumbo and mesh handler is used to pick up the high-tensile mesh roll and transport it to the unsupported area. Both the high-tensile chain-link mesh and its fully mechanised installation significantly increase the safety of mining personnel and rapidity of mining development. }, doi={10.36487/ACG_repo/902_15}, url={https://papers.acg.uwa.edu.au/p/902_15_Bucher/} }
