This was in response <br />to the Shaft Construction Plan submitted on November 7, 1994. <br />We were notified that the ventilation portion was okay following the January 26, 1995 <br />submission; however, that the roof control portion needed additional information. The plan <br />being submitted now has bold type where changes have been made to address the roof <br />control concerns. Several small changes have been made to the ventilation portion of the <br />plan. Those changes are desribed below and are noted in the plan with underlined bold <br />type. <br />Additional or revised drawings are noted below and several informational larger drawings <br />are attached to depict typical work deck and hoisting installations. Changes to the current <br />plan are described below: <br />Item 1. Page 1. 75.220 Exploration -This paragraph reworded to better describe the <br />potential of removing one or two roof bolts if the current primary support is in the path of <br />the 5-foot raisebore hole. <br />Item 2. Page 1. 75.220 Shaft Excavation -Wording changed to reflect that the raisebore <br />hole plug is for fall protection and that it will not stop ventilation flow. Also, wording added <br />that explains the safety precautions that will be followed during the mucking process <br />following shooting. Also, "permissible teletrams" has been replaced with "permissible <br />haulage units". <br />Hr~ROVED CM5 ~ H iii ~ P~ 2 ~ f ~ 5 <br />_. _ <br />- - T ------ - --- - ~-- .. --- - <br />
