Normal production blasting breaks to two faces and delays will all be non - electric. Non - electric <br />delays will be located on the surface and down each borehole to minimize the number of holes <br />detonating in any given 8ms time period. Use of non - electric delays reduces noise and <br />increases safety in a region of frequent thunderstorms. It should be noted that WFC may, at <br />times, use the new 'electronic, programed delay' system to achieve better fragmentation and <br />lower vibration in special circumstances. <br />A typical production, decked production and parting blast design can be examined in Appendix <br />2.05.3(6)(a) -4. These blast designs have been approved by a certified blaster. <br />6.0 Explosive Selection and Poundage <br />Rule 2.05.3(6)(a)(i) <br />Actual field experience at the New Horizon 2 Mine indicates a high percentage of the blast -holes <br />contain some amount of water. Since the startup of the mine, various water resistant products <br />and loading techniques have been examined and tried. New Horizon 2 Mine has settled upon <br />the use of: a) bagged gel products in conjunction with ANFO in plastic sleeved holes for slightly <br />to severely wet holes, and b) straight ANFO for the dry holes. Typical poundage of explosives <br />used per hole will range from 1 -600 pounds of ANFO /bagged -gel for full bench production blast, <br />1 -250 pounds of ANFO /bagged -gel for deck shots and 1 -40 pounds of ANFO /bagged -gel for <br />parting shots, see Appendix 2.05.3(6)(a) -4. It is not unusual to use all of the methods listed <br />above, along with loading conventional straight ANFO in dry holes in a single overburden blast <br />pattern. <br />7.0 Explosive Storage <br />Rule 2.05.3(6)(a)(viii) <br />There will be no explosives stored on the mine permit. All explosives will be handled and <br />transported by an independent contractor. The independent contractor will store all explosives <br />off of the mine permit, at their own facilities. <br />8.0 Blasting Procedures <br />SECTION 2.05.3(6)(a) PAGE - 7 - JULY 2013 <br />'7W -0,Z <br />IV/vrecJ <br />/ 7 • Jv/ .2 -OJ_3 <br />
