<br /> <br />Page 3 <br />~ Ucscription of Applicants Proposal <br />The Cameo seam has been accessed lrom ;i brncii rxcavaLCd nt lhr coal <br />outcrop. 'the exploration activity is to ue conducted ns au undery;rounu <br />operation. A 5-en[ry system has already been driven uuc cast approxi- l' <br />mately 1,4UU feet. From ti+e coal outcrop area to 1,hUU Ler.t true cast <br />a fault was encountered. <br />'three sets of taint probe entries may be urivcn co to n her identity tnc <br />orientation of the fault lines to the east anu west of the uxis[inL <br />entries. The development and direction of [he main entries will depend <br />upon the information acquired by the probe entries. t•'or the purpose of <br />the mining plan Sheridan Enterprises, Inc. plans on turning the main <br />entries to the northeast and devclo'ing pacallcl to Cl,u pro~cctcu fault <br />line. These 5-entries will loLlow ~+is bearing unCiL [he eastern lease <br />edge §arrier is reached. troin Ch is point Che mains will be [urneu <br />north and developed Co [he eastern lease cdl;c. wi+ere the mains cuange <br />direction tram northeast to a north~•r ly uirectiou, a J-entry (submains) <br />panel will be driven west to the pre•~ected coal ;can. outcrop. <br />As already mentioned, Che mains will consist o1 live entries; the two <br />outside entries will he used for return airways and tnc two adjacent <br />entries will be used for intake air. L+c bcL[ entry will be isolated <br />from Che intake and return airways by pcnu:n;cnl sCOppin~s. <br />Once exploration work is completed and [hc laults have de[initc <br />characteristics then panels will be developed olt me mains and <br />submains. These panels consist of one intake airway, one return airway <br />and one belt entry; and will be to the hurt 6wcsl. <br />1'he entries are planned [o Lc on 75 Lour centers wiU~ crosscut spacing; <br />01 lUU Ceet. 't'hese dimensions, enviously, arc dupenucnt upon the <br />geologic conditions of the Cameo scam. 'the entry widths an: planned <br />to bc'a minimum of Lb loot wide and a waximum ut 2U 1ect. Barrier <br />pillars of 2UU feet will be left [o protect the main entries. <br />k'anel entries are planned to ue on 45U toot centers. At [i+c enu o1 the <br />panels a bleeder entries will be driven 3UU ice[ back Co [ho pn,ceciing <br />panel. Rooms are Co be urivcn ull on panels and onto three rooms have <br />been urivcn; with Lwo sets u1 pilLars uovclupc~i; then cirr lirsL row of <br />pillars will be recovered. <br />1'he .icClane Canyon Nine is totally dependent upon [hc m.arxetability ut <br />the coal. dining for [he Lirst live years has Becn desi9;ned Cu <br />determine [he orientation and extent of the Laults. lot;,l production <br />Lor Che Ccnn oC [his permit area (duration is three years) is JLy,SUU <br />Coos. Annual production will bu approximately 123,000 tons/year. If <br />annual production is expanded in the second year to 'L46,000 tons [hen <br />the term of [he permit is reduced to two years. Y'he Cameo scam varies <br />in thickness lrom 17 to 12 feet. 't'he actual mining height of the Cameo <br />seam a[ [he McClave Ca+,yon mine will range from 1s to 13 lee[, i'anel <br />mining method will yield an overall recovery race of 4y~X. <br />
