.. EXHIBIT D <br />MINING PLAN <br />1. Description of methods of mining (See t9aps and Charts <br />at Exhibits C-1 thru C-5). <br />During site preparation vegetation will be removed from <br />the operational area which will consist of the crusher location, <br />limestone stockpile area, top soil storage area, limestone fines <br />fill area, new section of haul road and the initial quarry pit <br />area. It will be disposed of by either burning or by removal to <br />a solid waste disposal site. Next, topsoil from these disturbed <br />areas will be removed, segregated by horizon type and stored near <br />the operational area, The operational area will then be completed <br />by cut and fill benching to provide the necessary working areas <br />on the steep slope. <br />The limestone will be quarried by employing basic open <br />pit mining procedures. Benches will be developed in the solid <br />rock as indicated in Exhibits C-2 and C-4. Blasting of the <br />benches to produce shattered limestone is normally accomplished <br />two or three times a week. As many as one to two hundred 3" <br />holes are drilled about 20 feet deep a few feet apart in a bench. <br />A stick of dynamite (TOVEX) attached to primer cord is then <br />lowered to the bottom of each hole. The hole is then filled to <br />within about 6' of the surface with ammonia nitrate. The top 6' <br />is filled with dirt. An electric blasting cap is used to set off <br />the primer cord which in turn sets off the dynamite and ammonia <br />nitrate. This type of blasting produces a relatively mild explo- <br />sive boom and ground shock waves travel relatively short distances. <br />About a 20 foot layer of a portion of the ~aorking bench is simply <br />shattered in place. <br />
