<br />-3- <br />(5) In the event that the applicant proposes to prevent subsidence from <br />occurring, the 50' boundary would ue acceptable along the external <br />pennit boundary, assuming that the consultant's technical projections <br />are first verified above a panel within which the 16` x 16' slabbed <br />pillar is utilized. This would require selection of an appropriate <br />test panel separated from the external pennit boundary, to preclude <br />subsidence outside the permit area boundary if that pillar sizing <br />were to prove inadequate. This will require appropriate plan <br />configuration and scheduling, in order to accomplish the test panel <br />prior to mining and slaooing along the otherwise unperinittable permit <br />boundary. <br />/ep <br />cc: Ed Bischoff <br />Doc.
