On the day of the scheduled blast, the pre-determined amount of bulk explosive <br /> ingredients, explosives and blasting accessories will be transported to Hitch Rack Ranch <br /> Quarry in DOT approved vehicles that are specifically designed and equipped to carry <br /> explosives over public roads and highways. After blasts are loaded and shot, any <br /> ingredients, explosive products and blasting accessories not consumed in the day's blast <br /> are inventoried, volumes of bulk explosives and accessories used and unused will be <br /> documented, and all surplus materials are transported back to the third parry blasting <br /> contractor's licensed storage location in the same vehicles used to transport the explosive <br /> ingredients, explosive products and blasting accessories to Hitch Rack Ranch Quarry. <br /> The blasting contractor typically transports only the volume of bulk explosives to be used <br /> at Hitch Rack Ranch Quarry, thereby minimizing the amount of explosives, including <br /> cast boosters and initiation components, transported over public highways. <br /> Loading of Explosives <br /> On the day of a scheduled blast, the third party contractor's blast crews and trucks will <br /> arrive at Hitch Rack Ranch Quarry with predetermined and planned amount of non- <br /> explosive ingredients for the bulk explosives and blasting accessories. <br /> • On arrival at the blast location and prior to loading the blast crew will inspect the <br /> work site (bench) and drill pattern. The quarry manager and the third party <br /> contractor Blaster in Charge will review the Drill Log for the blast. The blast will <br /> not be loaded without a proper drill log. Hole depths and amount of water will be <br /> measured and recorded. The blast crew will survey the rock face in front of the <br /> drill holes located along the edge of the rock bench (front row)to determine what <br /> actual amount of rock burden is present. If angled drill holes were planned those <br /> holes are surveyed (using a boretrak tool) to measure actual angle and any <br /> deviation along there length. The result of this survey will determine how these <br /> holes will be loaded with bulk explosives and how much stemming will be <br /> required. The blast site is then established and warning signs are posted by the <br /> blast crew at any access road to the blast pattern. The blast site (i.e. a fifty-foot <br /> perimeter from any hole intended to be loaded, as defined by MSHA) is very <br /> restricted (no operating equipment except for that needed to load the blast), <br /> secured and monitored. <br /> • A cast booster with NONEL detonator properly attached (primer) is placed into <br /> each hole with the down hole lead line being secured at the collar or top of the <br /> hole. For bench heights above 28 feet, two primers will be placed in each hole, <br /> one at the bottom and one nearer the top of the bulk explosive column. <br /> 8 <br />
