and fuel oil (ANFO) prills. The blasts will be initiated using a non - electric system <br />(nonels) with the pattern of holes, firing sequence, and delays designed to allow for <br />optimum breakage and minimum ore dilution. All explosives for this operation will be <br />provided by a licensed contractor and stored in an underground magazine. There will be <br />no surface storage of explosives. <br />The ore and waste rock will be mucked out using small diesel loaders. Ore will be hauled <br />to the surface using low- profile, diesel - powered haul trucks (commonly called buggies). <br />Some of the waste produced during later development and production may be disposed of <br />underground. <br />Back support will consist of installing five foot to eight foot long split -set roof bolts. <br />Bolting will be performed as necessary with the spacing varying according to back <br />conditions and the size of the opening. Mine openings will be approximately twelve feet <br />wide in the drifts but may be wider in the stopes. Metal mats and mine -grade wire will <br />be installed in the back and diagonally on the ribs where additional ground support is <br />required. <br />Material storage areas and stationary equipment will also be located underground. Roof <br />bolts, mats, vent tubing, hoses, lubricants, and the smaller and more commonly used <br />equipment parts, will be stored underground near the working faces. These locations will <br />change as the mine workings are advanced. Stationary underground equipment will <br />include air compressors, transformers, and ventilation fans. <br />All surface equipment will be contractor owned, and therefore maintained offsite. Only <br />the underground equipment will be maintained onsite. <br />
