Survey of Electrostatic Hazards Detection and Minimization.
NTIS: PB/84-186709 Available for Reference At Bureau of Mines Libraries :116 pages
The objective of this study is to make a critical evaluation of the magnitude and extent of electrostatic hazards in typical U.S. mining operations and to assess the adequacy of techniques, materials, and equipment for detecting and minimizing these hazards. This was accomplished with an incident-accident survey, mine visits, literature search, and engineering analysis. It was concluded that it would be desirable to (1) utilize ground fault interrupters to minimize stray current from electrical utilities, (2) decrease the current and electrostatic sensitivity of electric detonators used in areas with a high incidence of lightning strikes or troublesome stray currents, (3) institute quality control and test standards for blasting material and protective devices, (4) establish an electrostatic monitoring program for loading ammonium nitrate and fuel oil in plastic-lined holes, and (5) establish risk criteria for operator exposure in mines.
