Comparison of Ground Support Systems

This essay discusses ground support that has been employed in underground mines in order to ascertain the security and protection of the personnel as well as the equipment working there as well as to fulfill the desired engineering purpose of the aperture. The rockmass around an aperture may be considerably fragmented and fractured as a result of the combination of stresses, discontinuities and also, because of the blasting activities for the production 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 ejection 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 1980's, Urylon Plastics Inc. (previously Guelph, Ontario) and in the present times, Mine guard Canada , in association with the Department of Mining Engineering at Queen's 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 research states that shotcrete is considerably more productive however it also is significantly more expensive and needs substantial amount of material handling. The material costs of spray-on liners are very much higher however they result in considerable increased productivity…
