Western Colorado Testing, Inc. performed a geologic evaluation for the original permit of this pit <br />(M-94-005). Testing at 1 H:1 V to 1.SH:1 V slopes generated a safety factor of minimum 1.26. <br />2H:1 V slopes were tested with an applied seismic acceleration factor of 0.25, as done in <br />California to test against high intensity earthquake potential, which generated a safety factor of <br />1.08. ;Colorado is simply not susceptible to these type seismic factors for such intense <br />earthquakes therefore, this demonstration shows that any reasonable assumption yields a safe <br />slope.
