2 <br />Portal airshafts, two intake airshafts located in Apache Canyon, and one slope at the <br />East Portal. <br />The Allen and Apache Seams will be accessed by driving development from the <br />slopes south and east in the Apache Seam above the old Allen mine works. Mining <br />will take place in either the Apache or the Allen depending on the coal properties. <br />Ramping down to the Allen will occur beyond the mined -out area leaving a barrier <br />pillar for safety between the old and new works. Development will utilize <br />continuous mining methods by pairing continuous miners with shuttle cars for coal <br />transport to a conveyor belt. Coal extraction will be achieved using room- and -pillar <br />mining with pillar recovery (secondary mining) where technically feasible and <br />legally allowed. No secondary mining is planned in any area where protection from <br />subsidence of surface structures is required. <br />The major mining equipment used at the New Elk mine is listed in Table 18 Mining <br />Equipment List. Surface facilities associated with the underground operation consist <br />of facilities necessary for the production and loading of coal into truck and rail cars <br />for transport. Ancillary facilities consist of shops, warehouses, administrative <br />buildings, and bathhouse. Operational facilities included ventilation shafts, <br />ventilation fans, escape ways, and production and supply slopes to access the Allen <br />Seam. Control of surface water in the surface facilities area is provided by ditching <br />and drop structures to sediment control structures for holding runoff for settlement <br />and/or treatment prior to discharge. Mine water is provided through small dams and <br />pump stations located adjacent to the Purgatoire River. Wastewater treatment is <br />provided by septic tanks and by a sewage treatment plant. <br />Table 18 Mining Equipment List <br />Continuous Miners <br />Feeder Breakers <br />Roof Bolters <br />Belt Drives with Structure and Belting <br />Shuttle Cars <br />Rock Dust Equipment <br />Man Tris <br />Supply Scoops <br />Electric and Diesel Powered Scoops <br />Maintenance Vehicles <br />Ventilation fans and Intake Heaters <br />Excavators and Backhoes <br />Track and rubber tired dozers <br />Front-end Loaders <br />Roads are required to provide access to the surface facilities of the mine.

A coal haulage road is employed in the transport of coal from the coal <br />processing and storage area to State Highway 12. <br />(2) Operation Description <br />The aerial extent of existing underground mine workings in the Allen Seam is shown <br />Section 2.05 RN -6 10/17/2016 <br />
