. (d) Blasting signs. Blasting will be used to dislodge the <br />overburden. then blasting is necessary, signs reading <br />"Blasting Area" will be posted at conspicuous places along <br />the access and haul roads within the property. These signs <br />will indicate blasting warnings and all-clear signals to <br />the permit area. Blasting records such as those on the <br />next page will be maintained in the office for inspection. <br />(e) Topsoil markers. Topsoil stockpiles will be marked with <br />topsoil markers that read "Topsoil". These markers will <br />remain on the topsoil stockpile until all the material has <br />been removed. <br />2.05.3 (I) Production Methods and Equipment <br />Pit 4 will be mined by a sequence of box cuts starting at the <br />lowest elevations and working up. Topsoil will be stripped separately <br />for each cut made to preserve existing ground cover as long as <br />possible. Topsoil will be stripped and stockpiled or placed over <br />backfilled and regraded previous cuts. <br />Earth overburden (unconsolidated material) will be excavated and <br />transported with rubber-tired scrapers. Excavated material will be <br />stockpiled (separately from topsoil) to await use in reclamation. A <br />motor patrol and water wagon will be used to maintain haulage routes <br />as required. <br />Rock overburden will be drilled and shot using rotary or percussion <br />drilling equipment. Dependent upon the nature of the rock and the <br />breakage achieved, one of two methods will be used to excavate and <br />transport the rock. <br />1. Rock will be excavated, hauled and placed with hauling units. <br />2. Rock will be excavated with loaders and loaded into trucks or <br />other hauling units for haulage and placing. <br />Dozers and loaders may transport the material short distances. <br />After the initial box cut has been opened and the coal removed, <br />the overburden from subsequent cuts will be placed in previous cuts to <br />begin the reclamation effort. <br />The top exposed surface of the coal will be scraped clean using a <br />motor aatrol, loader or other suitable equipment. Depending upon the <br />in situ density of the coal, one of two methods of removal will be <br />used in Pit 4: <br />1. Proposed Method: Coal will be excavated and loaded directly <br />into highway trucks with a backhoe or loader. <br />1 <br />2-85 III-3 <br />
