GENERAL-SURFACE AND UNDERGROUND (1) The employer shall establish a definite effective program <br /> and continually funcitoning safety program and make every attempt to prevent accidents and increase safety. Employes shall actively participate <br /> in the safety program. - <br /> NOTE ITEM CODE __ <br /> SECTION <br /> The following information was observed during monitoring of blastinc <br /> operations on May 8, 1989: <br /> Peak Vibration Measurements - Transverse, Vertical , and Longitudinal <br /> Peak Particle Velocities of 0.055 IPS at 14 Hz, 0.074 IPS at 11 Hz, <br /> and 0.062 IPS at 11 Hz, respectively, were measured. The Peak <br /> Vector Sum (or Resultant Peak Particle Velocity) was Os.09 IPS. <br /> Transverse, Vertical , and Longitudinal Displacements of 0.00150 in. , <br /> 0.00175 in., and 0.00192 in. , respectively, were also observed. <br /> Peak Sound was less than 110 decibels. <br /> • <br /> • <br /> Shot Information '- _This shot was composed of 5,016 pounds of <br /> explosives loaded into 45, 3 inch diameter, 50 foot deep drill <br /> holes, on an 8 foot by 8 foot pattern. The shot was detonated in a <br /> single deck; with a maximum charge weight of 140 pounds per delay. <br /> Weather at the time -of the shot was 55 degrees F, cloudy skies, and <br /> calm winds. No flyrock was observed outside the immediate blast <br /> area. <br /> As can be seen by the information plotted on the attached ILHR <br /> Chapter 7, figure 7.64, the blasting resultant vibrations observed <br /> fall well within the set limits. <br /> Blasters Logs Examination - In addition to monitoring ground r <br /> vibration for the May 8 shot, Ahlgrimm Explosives' blasting logs for <br /> work done at the Ziegler quarry were examined to determine the type <br /> and maximum charge weights detonated. There were three shots durinc <br /> the period April 17 to May 1 , 1989. The following is a summary of v <br /> that information. <br /> IMPORTANT <br /> • Please report when hazards are eliminated. <br /> • Avoid delay. <br /> • Keep us informed. <br /> HAZARD ELIMINATION DATE -SAFETY HAZARDS EXPLAINED TO: TITLE <br /> Rich Bingham Blaster <br /> BY C MINE SAFETY SPECIALIST SAFETY& BUILDINGS DIVISION <br /> Address all Correspondence Safety and Buildings Division,Mine Safety Section, Department of Industry, Labor <br /> and Human Relations,P.O.
