r <br />MINING PLAN <br />ALEXANDER PIT - NIELSDNS, INC. <br />Because of the scarcity of topsoil at this pit site, little or no <br />stripping is done before production starts. <br />A portable crusher is brought to the pit and set up for the size of <br />aggregate desired. Pit-run gravel is carried to the crusher by front end <br />loaders and dozers. Material is crushed and screened as required and then <br />stockpiled at the site. <br />Some of the material is then processed thru the washall machine to <br />obtain sand and gravel for concrete operations. Water discharged from the <br />washall is placed in settling ponds so that the fine sand and silt is <br />deposited away from the river. After completion of the washing operation, <br />this fine material is removed from the pond and stockpiled. The settling <br />pond may be used more than once in this way. <br />The raw material is removed in horizontal layers, and this forms a <br />bench on the gravel, giving the operator an area in which to set up his <br />equipment and stockpile. <br />
