WESTERN SLOPE CARBON, INC. <br />• MINE OFFICE -SOMERSET, COLORADO 83<3C <br />303~9i9~5B15 <br />September 4, 1979 <br />Mr. Bill Knepl. <br />Ventilation Department <br />MSHA <br />Denver, CO <br />Dear Sir: <br />Western Slope Carbon respectfully requests permission to use the <br />first four cross cuts of [he main belt as an intake air course. <br />In accordance with 75326 and 75-1707 C.FR. we would construct <br />steel doors in the fourth crosscut that could be shut tightly <br />in the even[ of a fire, so that the air from the belt would be <br />coursed into the return. Belt fire sensors would be moved from <br />125' to 50' for added protection. The drive assembly is now <br />protected with a dry powder type system. Doors will be built <br />• with 1/4" steel plate and hung on treated wooden frames.(See <br />attachment.) Our reasons for wanting this approval are: <br />1. Need for more intake air capacity immediately <br />2. To lessen restriction on mine ventilation <br />We would appreciate approval of this until March 1, 1980. <br />At the present time we are waiting for an approval from OSM <br />for a breakout. When the breakout is completed we would then <br />isolate the belt as before. <br />Sincerely, <br />Ralph Audin <br />Safety Director <br />RA:wp '~ -~ <br />: ~QD 0 X0,19 ~ <br />5 <br />~, :, <br />~'- , <br />u <br />A f U~ F I D I A A Y O F N O g T N W[ F T [ M F A G Y C O M F A N Y <br />
