The total <br />recoverable reserve base is dependent upon the alignment of the faults forming <br />the graben and the extent of burned coal found along the outcrop. The geologic <br />conditions shown in Figures 2.1-5 thru 2.1-9 and discussed in Sections 2.1.4 and <br />2.5 have been used to formulate the mining plan. <br />Total anticipated production will be limited to 0.3 to 0.5 million tons per <br />year as detailed in Figure 2.1-1. <br />•~ Future mining will primarily be location east of the graben. Access to the <br />east reserves is through rock slopes developed in 1991 to fhe upthrow block of <br />coal east of the fault. Rock generated from slope excavation was disposed of in <br />the mine. The location and orientation of the main mine entries takes into <br />account the various geologic anomalies that could interrupt or hamper mining. <br />The main entries stay away from areas of known geologic hazards so that mining <br />conditions should be relatively constant. Submains or rooms are then driven to <br />the permit boundary or into adverse conditions until their progress is interrupted. <br />Maximization of resource recovery will be attained by utilizing this mining <br />method. <br />McClave Volume 1 03/06 <br />
