Injection of FGD Grout to Abate Acid Mine Drainage in Underground Coal Mines

摘要

The Roberts-Dawson Mine acid mine drainage project is expected to provide a comprehensive examination of the efficacy of using power plant flue gasdesulfurization byproducts to remediate acid mine drainage. The project will attempt to demonstrate practical construction methods to drill, provide temporary drainage, inject and monitor placement of FGD grouts in the abandoned underground mine environment, and is expected to yield useful information on the technological and economic viability of this approach. The grouting process will be carefully monitored and documented, and its effects on surface and groundwater conditions will be assessed in detail. The project sponsors hope that successful completion of this demonstration project will lead to large scale beneficial use of power plant FGD materials in remediating acid mine drainage problems at Ohio's abandoned coal mines.rnThe project is scheduled to begin construction in August 1997, to be completed in December, 1997. Monitoring data assessing its effectiveness will begin to be available in 1998.
