Hydrochemical Impacts of Mine Waste Backfill in Underground Sulfide Mines.
Proc 2nd Intl Conf Env Issues & Mgmt Waste in Energy & Min Prod Balkema 2:891-902
The underground injection control program (uic) was promulgated in 1981 by the U.S. Environmental Protection Agency under the provisions of the safe drinking water act. The U.S. Bureau of Mines is investigating the environmental effects of backfill in anticipation of uic regulations. Impacts on water quality that can be attributed to placement of different backfills are being investigated in three underground sulfide metal mines. Water samples are being gathered from seeps both before and after water contacts the backfill. Concentrations of major ions and trace metals are compared among sites to identify differences that can be attributed to the backfill material.
