<br />2.1.3 Production <br />2-a <br />A total of 201,867 tons of coal were produced from the McClane Canyon Mine <br />during the 1991 to 1996 permit term. Future production rates from McClane will be <br />governed by the coal market. The mine will reinitiate coal production during December <br />w.1~ 2uc% r// <br />1999 or January 2000 at an initial production rate of 300,000 to 500,000 tons per year. ~ <br />The reserves to be mined are shown of 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 />• Total anticipated production will be limited to 0.5 million tons per year. <br />~~. <br />Production scheduling is detailed on Figure 2.1-1. ~r;~..";at"rw~'~ <br />Y~r <br />Future mining will primarily be located east of the graben. Access to the east <br />reserves is through rock slopes developed in 1991 to the upthrow block of coal east of <br />the fault. Rock generated from slope excavation was disposed of in the mine. The <br />location and orientation of the main mine entries takes into account the various <br />geologic anomalies that could interrupt or hamper mining. The main entries stay away <br />from areas of known geologic hazards so that mining conditions should be relatively <br />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 <br />attained by utilizing this mining method. <br />M`Clane Volume 1 ~ 12/99 <br />Ih 10 <br />
