Comparison of Ground Support Systems - Essay ExampleThis essay discusses ground support that has been employed in electric resistance mines in order to ascertain the security and protection of the personnel as well as the equipment working there as well as to save the desired engineering purpose of the aperture. The rock and rollmass around an aperture may be considerably fragmented and fractured as a entrust of the combination of stresses, discontinuities and also, because of the blasting activities for the turnout or development purposes. Also, pieces of rock, that may range from a few grams to many tones in mass, may fall or slough into the openings of the mine as a result of gravity. Moreover, rock can be violently dumped into the mine openings because of the seismic bursting. The support methods have been developed in order to avoid the falling or elision of the rock into the mine openings. Screen mesh, resin or mechanical rock bolts, and plain or reinforced shotcrete have been found to be the indispensable features of the production cycle of mining in Canada for year and have improved in the safety of the operator and the equipment along with enhancing the recovery of the minerals. Beginning from the late 1980s, Urylon Plastics Inc. (previously Guelph, Ontario) and in the precede times, Mine guard Canada , in association with the Department of Mining Engineering at Queens University and the MIROC - Mining Industry Research Organization of Canada created an innovative and new rock support system that is known as MIROC MineguardTM. MIROC Mineguard comprises of a thin, durable and highly flexible 2-component polyurethane spray-on liner. The RockguardTM is another polyurethane/polyurea hybrid liner, which has been developed by Futura Coatings incorporation in Missouri, USA, has become available recently. MineguardTM and Rockguard are considered as the best forms of spray-on liners and both of them will referred as polymer liner support in this study. The other spray-on products under exam and development are Master Builders epoxy-based product and Fosrocs latex-based Tekflex product. All systems have been demonstrated not only in the laboratory alone also in the underground so that they may work in a various ways. The technical aspects and properties of every support system have been put down well in the literature. Each support system has some technical constraints and benefits, but they will not be included in detail in this study. Although being technically sound with respect to engineering concepts, however, it is also vital to take in to account that whether it is also cost effective or not, and that how apiece method
