Map, (Map 18). Lazge or bulky items including tires, cable, roof bolts, <br />conveyor components, and mine timber aze typically stored in the surface <br />storage azea where they aze accessible but do not require closed storage. <br />EFCI maintains specific inventory control and material handling practices to <br />ensure that all materials and espeaally those which pose potential <br />environmental or safety hazazds are stored and handled according to <br />manufacturer recommendations and in compliance with all applicable <br />regulations. Such materials include explosives supplies which are stored <br />separately in an explosives bunker area, and petroleum fuels and lubricants <br />which aze stored separately in fuel tanks as discussed later in this section. <br />Upon completion of mining and related activities, the shop/ <br />office/wazehouse facilities will be demolished, unless retention of these <br />faalities is approved to support the postatining land use. The resulting <br />demolition debris will be placed at the base of the portal bench where it will <br />be covered by backfill material. <br /> <br />Coal Preparation Plant. Raw coal product from the mine is carried by the <br />main haulage conveyor to a raw coal stockpile located adjacent to the coal <br />preparation plant. From this stockpile, coal is reclaimed through a draw <br />point by an underground reclaim conveyor which transfers coal to the <br />preparation plant building. With the exception of the rotary breaker and <br />assodated systems, all coal prepazation equipment is located inside the <br />preparation plant building which is an enclosed structural steel building with <br />corrugated metal covering erected on a concrete foundation. <br />As raw coal enters the preparation plant it is first screened to separate the <br />coal into a 2" x 1/2" coarse fraction and a 1/2" x 0" fine fracton. The top <br />size materia] is tansfeaed to a heavy media vessel where fine magnetite <br />particles suspended in a water and chemical bath effect a gravity separaUOn <br />between the lighter coal fractions and the heavier mineral factions. From the <br />heavy media vessel, the coal float product discharges to dewatering screens <br />which remove excess moisture. The dewatered coazse coal product is <br />transferred to the clean coal product belt. <br />Minor Revision MR-41 2.05.3-23 Revised December 2001 <br />
