Abstract:
More than 70 quarry operations are conducted under the IML/A Category licence all over the country. The high demand of metal aggregates for the construction industry (road and buildings constructions) has made industrial quarry
operations one of the most profitable mining operations in Sri Lanka. However,
present economic situation and increase the number of I ML/ A category quarries in
Kaluthara District (13 quarries) causing problems in aggregate industry in this area.
Manufactured sand produced in quarries has become a better solution for scarce
sand resources as well as to increase the quarry operation revenue. During this
study three quarry sites in Kaluthara District were studied in detail and cost benefit
analysis was made. Among these TAMAC quarry site was the main source for the
study. Selection of a quarry site with low operation cost with minimum damage to
the environment plays the major role in success. Proper blasting techniques, crusher
plant design, selection of machinery and friendly environmental could increase net
profits and help to continue operations in a sustainable manner.
