Abstract
The Bureau of Mines has developed borehole mining equipment. This equipment has potential applications in environmental remediation and is especially suited for removing hazardous waste buried in situations where conventional excavation is not possible such as in urban areas. The method is selective and can extract deposits that are small or erratically distributed. This selectivity allows the volume of interest to be extracted without disturbing the surrounding rock or the overburden. Borehole mining has been proposed as a method for removing dense, nonaqueous phase liquids (DNAPLS) which have leaked into soils. DNAPLS cannot be removed by pumping of the groundwater and must be physically removed in order to remediate the groundwater. The borehole miner can also be used to backfill the mined out caverns to minimize subsidence or to emplace materials for controlling the flow of groundwater or modifying its chemistry.
