The following recommendations for monitoring of slope stability should be followed: <br />A visual inspection of the excavated high walls should be done on a weekly basis <br />for the first 6 months of mining. This inspection should consist of walking the <br />existing ground and looking for any signs of stress cracks or other potential signs <br />of slope failure. Some minor sloughing of high walls is expected on any mine site. <br />The intent of this inspection is to locate potential major slope failures that could <br />extend back into a structure. <br />A visual inspection should be done after a major precipitation event that has <br />saturated the ground using the same procedures. A major precipitation event <br />would be defined as a storm that produces an intensity level reached once in 50 <br />years on the average. <br />3. If a visual inspection detects signs of a potential slope failure, qualified personnel <br />should be contacted to evaluate and recommend remediation work to stabilize <br />the area. <br />4. If no visible signs of slope failure are detected within the first 6 months, then the <br />inspection period could be reduced to once per month or after every major <br />precipitation event. <br />NCCI Pit #1 <br />Sbpe Stability Analysis <br />Page 5 <br />
