| Resumen |
The transport of granular explosives and the placing of these explosives in boreholes may give rise, under certain conditions, to the accumulation of electrostatic charges, the extent of which is dependent on the type of contact (impact or friction) with the inside wall of the piping. The highest level of static charging was encountered following impacts. Experiments have shown that the conductivity of plastics or rubber piping varies in relation to the atmospheric humidity; the highest variation having been found in rubber, and the lowest in PVC. As for rock conductivity, the authors found that at their normal levels electrostatic charge is dissipated immediately. |
