1 from trees, cornfields around the area and <br /> 2 things like this. Thunder and wind get into <br /> 3 these things. <br /> 4 Natural cracks occur at about -- from <br /> 5 some studies now, because there's a million <br /> 6 studies out there if you want to read them -- 12 <br /> 7 to 13 cracks a year approximately. These would <br /> 8 be normal. <br /> 9 Questions? <br /> 10 MR. HANNA: How far away <br /> 11 from the blast? I'm talking about those cracks. <br /> 12 MR. BINGHAM: Okay. There's a chart <br /> 13 here, so to speak. Again, how far from the <br /> 14 blast. The distance from the blast is dependent <br /> 15 upon again your pounds per delay. t <br /> 16 So, for example, if I wanted to stay <br /> 17 -- I'm going to use a scale distance of 50 in my <br /> 18 mind here. I have a whole bunch of values for <br /> 19 that particular one. If I'm at 300 feet I can <br /> 20 use 36 pounds to stay above .3. I'm going to <br /> 21 take and move up to 1,600 feet away and at that <br /> 22 point I'm going to have a bigger bore hole, but <br /> 23 I can use 1,024 pounds and do the same thing to <br /> 24 a structure as I would with 36 at 300. <br /> 25 MR. HANNA: What size bore hole? <br /> 33 <br /> * * * CAPITOL CITY REPORTERS * * * <br />
