(d) 8lastin si~~ns. Blasting will be used to dislodge the <br />over ub rden. When 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 the <br />permit area. Blasting records such as those on the next page <br />will be maintained in the office for inspection. <br />(e) Topsoil markers. Topsoil stockpiles will be marked with top- <br />soil markers that read "Topsoil". These markers will remain <br />on the topsoil stockpile until all the material has been <br />removed. <br />2.05.3 (I) Production Methods and Equipment <br />Pits 4 and 5 will be mined by a sequence of box cuts starting at <br />the lowest elevations and working up. Topsoil will be stripped <br />separately for each cut made to preserve existing ground cover as long <br />as 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 patrol. 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 the strip areas (Pits 4 and 5): <br />1. Proposed Method: Coal will be excavated and loaded directly <br />into highway trucks with a backhoe or loader: <br />• <br />4.8=83 III-3 <br />
