Care should be taken when incorporating fault zone rocks into sellable construction materials as <br /> the highly altered and weathered nature of fault materials will likely yield samples that struggle <br /> to pass specification. Currently,the area featuring the exposed fault will be regraded and <br /> designated as a parking area to service both the proposed surface and underground mining areas <br /> and will, therefore, not provide a hazard with respect to mining. <br /> Figure 6. Photo of the northeast-southwest trending faults and shear zone in the drill and blast <br /> surface quarry area. Red and tan coloration with vertically oriented faults represents the—20 foot <br /> wide zone.Notice rain drops on the photo and lack of preexisting moisture seep from the fault <br /> zone. View to the northeast, photo captured 180906. <br /> Joint Stability—Underground <br /> Currently, Rose Red Quarry's production comes from the horizontal entries that extend into the <br /> hillside in a northerly direction at the north end of the site (Figure 7). These entries are <br /> supported by pillars that reduce the roof span to ensure roof stability. During the site visit, no <br /> visible rock block movements or signs of excessive loading in the sidewalls, roof, and floors <br /> Rose Red Quarry Geotechnieal Report 11 c:rcg I—acki and Assaciatte,PLIA' <br />
