2.05.3 <br />The applicant has applied for a lease modification to move the lease line <br />approximately one quarter mile to the east. The 2nd East Mains will be <br />advanced towards the east lease line. Mining will then be turned to the south <br />in the 1 st South Mains. There are five years or more of mining to the south <br />as shown on Figure 2-1-1. The applicant cannot predict when mining will <br />resume. <br />The coal reserve west of the graben will be evaluated for economic recovery <br />before final mine closure. The 2 West Mains will be extended to the graben <br />to determine if crossing the graben is feasible. A decision will be made at a <br />later date whether to drive ramps to the lower seam off of the 1st North <br />Entries. This block of coal may be developed depending on data collected <br />during the advance of the 1 st North Entries. Any decision to abandon these <br />areas will be made in consultation with the BLM. <br />Because of the variable geologic conditions that exist within the McClane <br />Canyon Mine reserve block, panels are designed so that known areas of <br />adverse mining conditions will be intersected near the end of the panels. This <br />design will allow adjustment of panel length to fit the reserve and enhance <br />the recovery ratio in the area. The panels shown on Figure 2.1-1 were <br />designed with "square" ends. The ends of these panels may be angled to fit <br />irregular features. <br />The following table shows the major equipment to be used in the mine and <br />on the surface. <br />PR -02 2.05-5- 10/12 <br />
