7.6 SEALING OF DRILL~ID HOLES AND UAIDERGFd~UDID OPENIN(',S (4.07) <br />• The sealing of exploration holes has been approved in TBM's <br />Notice of Intent to Conduct Exploration Work at the mine and the <br />reader should consult that docimpnt for sealing techniques. Holes <br />that will be mined through will not be permanently sealed but will be <br />t~g~orarily sealed if they will not be mined through within six months. <br />Any abandoned underground mine workings will be sealed during the <br />nornal backfilling process. No special techniques will be used to seal <br />these old workings unless serious water problems exist. At this time <br />water problems are not anticipated. <br />• <br /> <br />VII-9 <br />
