NMD (Panels 12 Right through 16 Right)(PR 99-OS) <br />Twentymile coal Company will continue to mine the reserves it controls in the Twentymile Park Basin. The mine <br />will move its operation into the Northern Mining District as shown on Map 23, Mine Plan Map. TCC controls all <br />of the coal required to mine in this area. TCC projects annual coal production at 10 million tons per year. <br />TCC uses the longwall mining method as the primary technique for ensuring maximum recovery of the resource. It <br />is planned to install a 1000' wide face and panel length ranging from approximately 13,600' to 17,000' in the <br />Northern Mining district during this permit term. The gateroads, main and submains will be developed by <br />continuous miner, as is the current practice. <br />NMD -14 Right Gateroad Alternate Location (MR O1-171) <br />Currently, TCC is in the process of evaluating if the 1000' wide face can be increased to approximately 1200' or <br />wider. The outcome of the evaluation may limit the face width to something less than 1200'. In order to <br />accommodate this uncertainty, and initiate the start of the gateroad, an area is shown in red on Map 23 and 23 B <br />for potential area in which the 14 Right Gateroad will be started. In the event that the evaluation determines that <br />the 1000' wide face is the correct width for TCC's conditions then the location of the gateroad shown on Map 23 <br />and 23 B will be followed. <br />NMD (Panels 17 Right through 21 Right)(PR 03-06) <br />Twentymile coal Company will continue to mine the reserves it controls in the Twentymile Park Basin.
