2.05.3 <br />(2) Operation Description - Underground Mining <br />The proposed surface disturbance associated with the underground mining activities <br />within the permit area include; 1) haul roads; 2) access roads; 3) a utility corridor; 4) <br />benches for mine facilities; 5) a gob pile and 6) unit train loadout. The area has <br />previously been disturbed by the construction of access roads for property <br />management and mineral exploration and the long term operation of the old King <br />Mine. To the extent possible, the existing access road corridors were integrated into <br />the surface disturbance. <br />The proposed disturbed area is shown on the Mine Facilities Maps Nos. 15-1, 15-2, <br />15-3 and 15-4. The Mine Plan Maps No. 14 & 14-B present the proposed <br />underground development schedule. <br />1. Haul Roads <br />One haul road will enter the property from old State Highway 133. The traffic on this <br />road will flow one of two directions. The first will be access to the mine facilities <br />area which is located about 9,500 feet from the highway. This road rises about 800 <br />feet from the old State Highway. The second traffic direction will be to the gob pile. <br />This road will traverse to the east along a rail road siding bench previously utilized <br />by the old King Mine operation. The gob pile is located east of the mine entrance <br />below the old King Mine portals. <br />The second haul road will begin near the base of the coal preparation plant and <br />traverse south and east across Bowie Road (State Highway 133B) near MM 13.2. <br />The grade of the haul road will vary between 2% and 10% as it declines in elevation <br />from the preparation plant to Gob Pile number 3. <br />2. Access Roads <br />Access roads are to be constructed from the main haul road to the utility corridor as <br />shown on the Mine Facilities Maps 15-1 and 15-2. An access road was also <br />constructed from the portal bench to the utility bench. <br />3. Utility Corridor <br />A utility corridor was constructed to provide a cleared route for the water line, power <br />line and downhill conveyor. The proposed surface disturbance is a steep corridor <br />about 3,000 feet long. <br />TR-49 2.05 - 7 - 08/07 <br />AfFA6vGJ> <br />C/Y/a1
