PROJECT APPROACH <br /> The field study was preceded by a careful examination of existing geologic information. <br /> For this project, the resources available at the Colorado School of Mines and the United <br /> States Geologic Survey were utilized to obtain a wealth of information in the form of <br /> reports and maps, relative to the Rocky Mountain Front Range geology and more <br /> specifically, the geology in the Morrison Quadrangle. This information, along with an <br /> assessment of geologic features interpreted from aerial photographs, courtesy of Mobile <br /> Premix, was used to develop a general understanding of the controlling regional and local <br /> geologic conditions. <br /> i <br /> Following this review, a program for quarry inspections was developed. The objectives of <br /> 1 the inspections were very specific and included the following: <br /> ' Identify and characterize the quarry geology. <br /> • Verify and record controlling structural features identified in the aerial photographs. <br /> I 0 Record the existence and location of ground water. <br /> • Study the mining method being used relative to drilling and blasting techniques, <br /> bench heights, slope geometry and reclamation. <br /> • Identify and photograph mechanisms of failure (if any) along each quarry wall. <br /> • Locate and record any obvious slope instabilities. <br /> iMap and photograph geologic discontinuities along each quarry wall. <br /> These objectives were accomplished by performing one-day inspections of the quarry <br /> quarterly, followed by a one week intense geologic mapping effort and subsequent <br /> analysis of the data. <br /> The mapping procedures were somewhat restricted due to the Spec-Agg Quarry Safety <br /> Policy, which prohibits anyone from getting within 50 ft of the quart'walls. Measurements <br /> 3 <br />
