Estimating Reserves Of Stone And Sand For Use By The Construction Industry

It is no longer possible to establish a quarry on the most convenient hill then abandon the site, leaving a scar if the stone or sand in the deposit is found to be unsatisfactory. Before approval is given to operate a new quarry, the relevant authorities require a detailed plan of operations from commencement to final rehabilitation. To prepare this plan, a thorough know- ledge of the quality and size of the deposit is required. To obtain this information, the industry must use the most modern techniques available. Many examples can be given showing problems which have affected the smooth operation of a quarry for many years because the initial exploration was poorly carried out. The factors which must-be considered when exploring a deposit are detailed in this Paper.
