Southfield Mine <br />Minor Revision Request No. 16 <br />South Fan Installation <br />Surtace disturbance will be minimized during powerline construction to <br />the extent possible and surface vegetation will be preserved ~pr <br />reestablished through seeding and mulching of disturbance sites. I 1 "~1„ „ ,~ <br />V~J V '~i \ ~ <br />Stabilize Mine Entries and Construct Seals <br />The existing main entry for the Monarch No. 4 Mine will be utilized as <br />the discharge airway for the proposed fan installation. In order to insure <br />the long-term integrity of the airway and provide for effective airflow, <br />EFCI will clean any loose rock or other debris from the main entry, place <br />timbers, rockbolts or other support as necessary, and construct <br />permanent stoppings or seals on intermediate panel entries. <br />It is anticipated that EFCI will construct 5 permanent seals as shown on <br />the South Mine Fan Installation Map, (Map MR16-1 ), to isolate the <br />discharge airway from the connecting mine workings. Seals will be of <br />approved MSHA design consistent with EFCI's existing ventilation plan. <br />Areas inby the seals will be timbered, bolted or otherwise supported to <br />prevent caving which could affect the seals. <br />Construct and Install Foundation, Fan Housing, Fan and Associated <br />Components <br />Upon completion of all necessary preparatory work, EFCI will construct <br />foundation structures for the ventilation fan, drive motor, control <br />equipment and fan housing. Foundation structures will be designed and <br />constructed to provide effective support for fan components and to <br />effect full compliance with applicable MSHA provisions under 30CFR <br />75.300. The foundation structures will be constructed of concrete, <br />block, or timber materials consistent with designs. <br />c: xork pq is rena B.B~ <br />12/2J/Bt apm 11 <br />
