~; <br /> <br />^QUARRYING <br />Drilling and blasting is used to liberate virgin stone from its natural consolidated state. <br />Haul trucks are typically used to take the.material to the plant for processing. <br />C~ICRUSHING (PROCESSING) <br />Processing can consist of as many as 4 different stages of crushing. Screening <br />between crushing stages allows for different product types. Water may or may not <br />be used for material washing, but dust suppression is necessary. <br />IbSTOCKPILING <br />(Check if applicable) <br />C~Overburden and topsoil <br />Stockpiles may occur in the form of earthen berms. <br />C~Sand and Gravel: <br />Raw and processed aggregate are stockpiled for future sales. <br />^Aggregate mix for concrete production: <br />Aggregate can be stored in stockpiles, and loaded into a ground hopper as needed; <br />and then conveyed to the plant, or loaded directly into a series of hoppers located <br />above the plant which directly discharge into the plant. <br />i <br />Aggregate mix for asphalt production: <br />Raw material can be stockpiled or put into storage tanks. <br />C~IRECLAMATION <br />Reclamation is an ongoing activity throughout the life of a pit or a quarry, and takes <br />place in a contemporaneous fashion as is practicable.
