Strata Proximity Systems Underground Generator Users Manual v1.0
Confidential and Proprietary
October 5, 2011
1.4.1.1 MSHA Blasting Distance
MSHA approval requires that a minimum of 40 inches shall be maintained between the
Underground Proximity Generator and any blasting circuits, explosives or detonators.
1.4.1.2 Pennsylvania Blasting Distance
Pennsylvania approval requires that the Underground Proximity Generator must be installed at
a minimum safe distance of 17 feet from blasting circuits, explosives, and detonators.
Note: Pennsylvania generates such requirements by multiplying the MSHA determined
minimum distance of 40 inches by a factor of 5.
SPS magnetic field generators produce a magnetic field that at 100 kHz or .1000 MHz does not
achieve the Critical H Field until 1.42 m with a blasting cap having a pickup area of 10 sq.
meters.
SPS magnetic field generators are safe to 1.42 m from the blasting caps. SPS does recommend
a minimum distance of 25’ as a precaution.
