Abstract
The Bureau of Mines has installed passive water explosion barriers in two operating mines to determine their usefulness in U.S. coal mines. The primary objective of this field trial was to determine the effect of the explosion barriers on mining operations. Data were also obtained on the ability of the barriers to withstand the mine environment and on the effect of the barriers on belt operation, ventilation, worker travel, and rock dusting. Fifty barriers were installed at three separate beltway locations, and periodic inspections were made. A year after installation, no defects of the barriers or support hardware were detected, nor was any complaint as to the presence of the barriers made by the mine personnel. To date, 2 1/2 years after installation, the barriers have had no detrimental effect on rock dusting, belt operation, or ventilation. Costs of material, fabrication, and installation are reported herein.
