Abstract:

An alternative to conventional stream sealing techniques was field tested at two

sites, one overlying shallow abandoned mine and another overlying an active

longwall mining operation. The alternative uses of polyurethene and

hydrological, and geophysical prospecting technology has proven to be a viable

technique for sealing damaged or leaking stream channels. Economic and

environmental advantages have been observed with this new technique, as well as

the virtual elimination of any future maintenance costs.
