Development of Tests and Criteria to Evaluate Grounding Systems.
NTIS: PB/81-238354 :176 pages
This report covers several aspects of mine safety ground systems, primarily for underground coal mines. The design of a combined ground fault-ground check monitoring system is presented. An analysis is made of grounding systems for DC shuttle cars. Complete resistance data and results of physical inspections of self-salting ground rods are presented. A detailed resistance and economic analysis is presented for the use of composite materials for building inexpensive and effective ground beds in high-resistivity areas. The desirability of penetrating the coal seam with a borehole safety ground is investigated. A report is made of a mine substation grounding and bonding workshop.
