|in March 1999, the School of Mining Engineering at the University of New South Wales carried out a series of underground trials using " Evermine", a South African developed two-part water based polymer membrane. The aim of the trials was to determine the potential of a spray-on polymer membrane such as Evermine as an alternative to conventional rib support systems The mine selected was Angus Place colliery, reputed to have some of the worst ground conditions of any Australian underground coal mine. Ribs at Angus Place are supported by conventional pattern bolting supplemented by wire mesh. The trials indicate that there is significant potential for the introduction of polymer membranes into the underground coal minim; industry Initial results indicated that ribs that had been sprayed exhibited less displacement and spalling than unsprayed ribs. particularly when subjected to abutment loads from an approaching long-wall Further research will he required to conclusively rate the performance of Evermine in comparison to other products in the market and the long term performance of the product|
