MINIING AND F;ECLAMATION January, 1986 • <br />WE:iI~ ELK MIME Revised March, 1987 <br />Revised September, 1987 <br />Revised August, 1991 <br />3.2.2.4 Haul Road <br />The main access to the West Elk Mine site and surface facilities will be from anew <br />haul road which will leave Colorado State Highway :133 approximately 1.3 miles east <br />of :iomerset, Colorado. This haul road will serve as the primary access for <br />personnel, equipment, supplies, trash, refuse hauling and coal hauling. Although <br />West Elk Mine coal is shipped primarily by rail, some coal is trucked from the mine <br />site or transferred to various handling or stockpile facilities on the mine site. <br />The existing main mine access will remain to access the silos and other areas of the <br />lower mine site. <br />The certified engineering design, specifications, and drawings for the existing haul <br />road are contained in Volume 5, Exhibit 3.1.1.D. The haul road is located entirely <br />within the permitted disturbed area of the West Elk Mine. Drawings MG-02-11, C-001 <br />through C-005 show the road plan and profile. The existing road is 7,200 feet in <br />length. From station 1+00 to station 35+50 the road has an overall vertical grade <br />of 5.68%, a maximum vertical grade of 11.52%, and is 3,450 feet in length. From <br />station 35+50 to station 72+00 the road has an overall vertical grade of 6.85%, a <br />maximum vertical grade of 12.18%, and is 3,650 feet in length. There are no areas <br />of t:he existing or new haul road where more than 300 feet of grade in any <br />consecutive 1,000 feet exceeds 10%. <br />The existing haul road widths are sections ranging from 24 to 32 feet in width. <br />Maximum cross slope is 2.0°l0. The new haul road is approximately 3,000 feet in <br />length and the pavement width is 24 feet. The maximum grade of the east-west road <br />segment is 5% and of the north-south segment is 8.5%. Designs for the new haul road <br />are contained in Volume 12. <br />The existing haul road has been paved with asphaltic concrete per Exhibit 3.1.1.D, <br />Earthwork and Utilities Specifications, subject to the geotechnical recommendations <br />found in Exhibit 2.7.9.6, Mt. Gunnison No. 1 Mine Landslide Studies; Exhibit <br />3.2.2.8, Geotechnical Site Evaluation--Proposed Mt. Gunnison No. 1 Mine Surface <br />Facilities; and in Exhibit 3.1.1.D, Earthwork and Utilities Specifications, <br />Divisions 1 and 2. The new haul road will have a nine inch pavement section <br />consisting of six inches of road base and three inches of pavement. <br />Ditches alongside the mine site roads facilitate both roadway drainage and plant <br />site drainage, as prescribed in federal and state regulations. Exhibit 3.1.1.D, <br />Earthwork and Utilities Package, Drawings 11 through 13, give specific design <br />information. Appendices A-9, B-8, B-9, C-1 and C-2 contain additional or revised <br />road and ditch designs. The new road drainage plans are shown in the designs in <br />Volume 12. <br />• <br />• <br />3-16 <br />
