2-15 <br />• Because of the variable geologic conditions that exist within the McClave Canyon Mine <br />reserve block, these panels have been designed so that known areas of adverse mining <br />i <br />conditions will be intersected near the end of the panels. This design will allow adjustment of <br />panel length to ftt the reserve and enhance the recovery ratio in the area. The panels shown on <br />Fgure 2.1-1 were designed with "square" ends. The ends of these panels may be angled to fit <br />irregular features. ~ <br />The production panels have generally been designed to allow for typical room and pillar <br />mining but will also allow for extraction using longwall methods. There has een no decision to <br />use the longwall extraction method to date. When the mains and submains have been driven to <br />i <br />the edges of the property, knowledge of the geologic conditions will be enhanced. This <br />knowledge is imperative prior to committing to longwall mining. DMG and BLM will be notified <br />i <br />•- and the proper revision will be approved prior to engaging in longwall mining'. <br />i <br />• <br />Nlo Volume 1 ~ 4-29-96 <br />
