Revised 11/15/81 <br /> to the Purgatoire River. All water utilized for sanitary and showering <br /> purposes passes through a sewage treatment plant prior to discharge. <br /> Several light use and access roads are required to provide access to the <br /> facilities of the Maxwell Mine. These roads include employee access and <br /> service and maintenance roads to associated water storage tanks, pump <br /> stations, ventilation fans, and supply yards. In addition, coal <br /> processing waste is hauled from the processing plant to a coal <br /> processing waste bank. Power for the operation of the mine is provided <br /> through overhead powerlines to the surface facilities. <br /> The surface facilities associated with the Maxwell mining operation <br /> occupy a relatively small area. The compact nature of placement of the <br /> shops, warehouses, and processing and transportation facilities provide <br /> for efficient operation of the Maxwell Mine. It is anticipated that <br /> very little additional surface will be disturbed by the surface <br /> facilities. Additional area will be required for disposal of coal <br /> processing waste and to locate ventilation and escapeway shafts as the <br /> mine operation continues development. <br /> Operation Description <br /> The area which will be affected by the Maxwell Mine is shown on the Mine <br /> Plan Map (Map 3). Development of the Maxwell Mine was begun in 1976 <br /> through inclined slopes south of the Purgatoire River. Continuous <br /> miners with associated support equipment have been utilized to continue <br /> development of the ventilation and haulage entries for the life of the <br /> mine operation. The mine development increase is currently being driven <br /> towards the northwest and southeast from initial entry point into the <br /> Maxwell Seam. During the next five years, development of these main <br /> entries to submains which run perpendicular to the main entries will <br /> continue. Following completion of the sub-mains, panels which will be <br /> utilized by longwall , shortwall , or other methods will also be <br /> developed. In addition, room and pillar sections will be mined where <br /> geology, coal thickness, or configuration of the block does not permit <br /> removal of coal by other methods. In addition, subsidence will be <br /> controlled to preclude damage to surface features and environmental <br /> 2.05-4 <br />
