<br /> <br />3 <br />• or diamond drill stations will be driven, and, before mining commences <br />on any ore block, the ore zone will be delineated further by under- <br />ground test holing. <br />After development is complete, ventilation is adequate and a <br />second escapeway has been provided, a modified room and pillar <br />stoping method will be used to mine the ore. This stoping method <br />is similar to the one presently used in the Uravan t1ineral Belt, <br />i.e., leaving waste pillars, and ore pillars wherever necessary for <br />roof support. The equipment and methods described in the develop- <br />ment phase will be utilized in the mining phase. <br />WATER CONTROL <br />From exploration drilling and a knotirledge of what the mines of <br />the general area have encountered in the past, no water problem <br />is expected. If any amount of water in encountered, it will be <br />pumped to the main sump, clarified, and then pumped to a surface <br />evaporation pond. The pond will be constructed if and only if <br />water is encountered in excessive amounts. <br />VENTILATIOPI, RADIATIOIJ COIJTROL AP:D SECOND ESC APE WAY <br />Initially air will be incast by a 50 HP single stage fan <br />through 30 inch diameter vent tubing and exhaust back through <br />the main decline. After the decline is completed, a ventilation <br />hole (seven foot diameter) will be upreamed, fitted with a fan, and <br />incast approximately 100,000 CF14. <br />As the development proceeds away from the bottom of the decline, <br />additional intake and exhaust ventilation holes will be installed <br />• as needed in conjunction with breakthroughs to contiguous mines. <br />
