This shows that the plan can be accomplished with the soil on site, but it does <br />not mean that there will be soil left over. All soil will eventually be used for reclamation. <br /> <br />As can be seen from Table 2.05.4(2)(d)-3, there is sufficient topsoil and subsoil volume in the <br />stockpiles to complete the topsoil redistribution plan. Since stockpiled soil had rock fragments <br />removed during stripping, the recovery from stockpiles is treated as 100%. The basic calculation <br />of the topsoil required in a given zone is: <br /> <br />Topsoil Needed Zone Area ac Soil Thickness inft <br />ac <br />in ft <br />ft <br />yd <br />()*, * () <br />* <br />43560 <br />12 27 <br />2 <br />3 <br />3 <br /> <br />The size of the stockpiles is determined via detailed surveys conducted on site. All soil thicknesses <br />are designed to the nearest inch, since this is the practical measurement limit for the scale of <br />equipment used at the New Horizon Mine. <br /> <br />North of BB Road/West of 2700 Road <br /> <br />Several areas are remaining to be topsoiled north of BB Road and West of 2700 Road.
