Martin Marietta Materials <br /> Spec-Agg 2016 Annual Report <br /> Ultimately, a total of nine (9) discontinuity sets were identified and analyzed for this annual report's <br /> structural discontinuity analyses. The discontinuity orientations are shown in Figure 7 and summarized in <br /> Table 1 below. <br /> Table 1: Representative Discontinuity Orientations <br /> Representative Orientation (Dip/Dip Direction) <br /> Discontinuity Set 2014 Annual Report 2015 Annual Report 2016 Annual Report <br /> F-1 (Foliation) 330/1700 34°/1700 330/1700 <br /> F-2 (Foliation) 220/2570 24°/2500 220/276° <br /> F-3 (Foliation) Not observed Not observed Not observed <br /> P-1 (Joint) 740/1720 740/1720 720/1750 <br /> P-2 (Joint) 590/0870 560/0840 570/0880 <br /> P-3 (Joint) 680/2550 680/2560 680/2560 (unchanged) <br /> P-4 (Joint) 670/301° 720/2990 740/299' <br /> P-5 (Joint) 680/3540 68°/3540 680/354° (unchanged) <br /> P-6 (Joint) 590/0250 60°/024° 590/0280 <br /> P-7 (Joint) 630/2200 650/2150 650/2150 (unchanged) <br /> 6.2 Slope Geometry <br /> Wall orientations used in this report are based on the mine plan developed by Martin Marietta in <br /> December, 2003 (Figure 2). The wall designations, slope angles, and slope dip directions used to <br /> represent the final quarry walls are presented in Table 2 below. <br /> Table 2: Representative Quar Wall Orientations <br /> Wall Designation Slope Anglellj Slope Direction of Wall(2) <br /> East Wall 1 45° 242° <br /> East Wall 2 45° 270° <br /> Northeast Wall 1 350 1750 <br /> Northeast Wall 2 45° 2250 <br /> Northeast Wall 3 450 1760 <br /> Northwest Wall 350 1510 <br /> West Wall 1 450 0910 <br /> West Wall 2 450 1200 <br /> West Wall 3 450 0910 <br /> Southwest Wall 1 450 0160 <br /> Southwest Wall 2 45° 0360 <br /> South Wall 450 0000 <br /> Southeast Wall 1 450 1 3350 <br /> Notes: <br /> 1 Slope angles are measured relative to the horizontal. <br /> 2 Slope orientations are presented as dip directions measured from true north (0°). <br /> February 8, 2016 Page 6 Lachel & Associates, Inc. <br /> Project 15364004.00 ©2016 All Rights Reserved <br />
