2-4 <br />2.1.3 Production <br />A total of 201,867 tons of coal were produced from the McClane Canyon Mine during the 1991 to <br />1996 permit term. In 1997, 49,115 tons were produced. The mine was idle during 1998 and 1999. <br />The mine reinitiated coal production during February 2000 and produced 305,332 tons in calendar <br />year 2000. <br />The reserves to be mined are show on Figure 2.1-I. The total recoverable reserve base is <br />dependent upon the alignment of the faults forming the graben and the extent of burned coal found <br />along the outcrop. The geologic conditions shown in Figures 2.1-5 thru 2.1-9 and discussed in <br />Sections 2.1.4 and 2.5 have been used to formulate the mining plan. <br />Total anticipated production is detailed in Figure 2.1-1. <br />Future mining will primarily be located east of the graben. Access to the east reserves is <br />through rock slopes developed in 1991 to the upthrown block of coal east of the fault. Rock <br />generated was disposed of in the mine. The location and orientation of the main mine entries takes <br />into account the various geologic anomalies that could interrupt or hamper mining. The main <br />entries stay away from areas of known geologic hazards so that mining conditions should be <br />relatively constant. Submains or rooms are then driven to the permit boundary or into adverse <br />conditions until their progress is interrupted. Maximization of resource recovery will be attained <br />by utilizing this mining method. <br />Mc Volume 1 October 17, 2001 <br />
