A five-entry system will be used for all of the previously described development work. The two <br />outside entries would be used as return airways. The belt entry would be adjacent to one of the <br />return airways. The remaining two entries would be used for intake airways. Depending on <br />conditions, entry and crosscut spacing will vary from 75 to 100 Feet and width from 16 to 20 feet. <br />See Figure 2.3-1. <br />The described development work for the Cameo and Carbonera seams is projected to take place <br />in years 1 through 5 of the project and is the only mining planned for this permit application. A <br />description of possible future development and secondary mining methods follows. <br />Future Cameo Development <br />As shown in Figure 2.1-4, GVC plans to develop mains north along the eastern lease barrier <br />pillar. These would originate at the eastern extension of the developed main entries and would take <br />place sometime in year 6 or 7 to recover the coal between this mine and the McClane Mine located <br />to the north that is not mined from the McClane Mine. <br />Secondary Mining <br />As development entries reach their limits, panel entries will be developed and room and pillar <br />mining started. Panel entries utilizing a 3-entry system will be driven offof the main entries on 450 <br />foot centers. <br />One entry will be used fbr the intake airway, one for the return airway with the third being the <br />belt entry. Entries are planned to be 18 feet wide on 75 foot centers, although this may vary with <br />conditions. Crosscut spacing will also vary. Barrier pillars, of approximately 20 feet will be left to <br />insure the longevity of the main entries. When panels have been developed to their furthest extent, a <br />bleeder system will be developed by driving connecting entries between panels. Battier pillars will <br />be left to protect the bleeder entries. Rooms wall be mined off of the panel entries a'distance of 300 <br />feet to the preceding panel. When three rooms have been developed, the first set of pillars will be <br />recovered. Mining will retreat in this fashion until the main entry barrier pillar is reached. <br />2.1.2 Life of Mine <br />The life of mine will naturally depend on the marketed volume of coal. Production rates will be <br />governed by the potential for distribution. Geologic conditions, such as the fault described in <br />Section 4.2.3 may also affect the life of the operation. For purposes here, the life of the mine is <br />estimated to be 30 years. <br />2.1.3 Production <br />M~ Page 2. I - 4 10-12-00 <br />
