2-4 <br />The reserves to be mined are shown on Figure 2.1-1. The total recoverable <br />reserve base is dependent upon the alignment of the faults forming the graben and the <br />extent of burned coal found along the outcrop. The geologic conditions shown in <br />Figures 2.1-5 thru 2.1-9 and discussed in Sections 2.1.4 and 2.5 have been used to <br />formulate the mining plan. <br />A production of 500,000 clean tons per year was used to prepare Figure 2.1-1. <br />Future mining is location east of the graben. Access to the east reserves is <br />through rock slopes developed in 1991 to the upthrow block of coal east of the fault. <br />Rock generated from slope excavation was disposed of in the mine. The location and <br />orientation of the main mine entries takes into account the various geologic anomalies <br />that could interrupt or hamper mining. The main entries stay away from areas of known <br />geologic hazards so that mining conditions should be relatively constant. Submains or <br />rooms are then driven to the permit boundary or into adverse conditions until their <br />progress is interrupted. Maximization of resource recovery will be attained by utilizing <br />this mining method. <br />MR -50 M° -Volume 1 (Rev 04/14) <br />
