Our secondary escape hoist (For Zone 2)was inoperable do to Ice build up in the raise. Pulled EE'S out of the Zone 2 & reversed intake fan to exhaust fan & thawed the ice. Hoist was put back into operation on 1/16/08 at approx. 12:16 Pm. This mine has 3 different escape hoists at this Mine site, please do not say this is a duplicate and reject this 7001 report.
