Title: Test plan for evaluation of the low-temperature thermal resource in flooded underground mines

Technical Report ·
OSTI ID:6400566

A test plan was developed to provide the basis for field measurements of the thermal resource associated with the waters of flooded, abandoned coal mines in Scranton, Pennsylvania. These waters provide a potential resource for a district heating and cooling project. The major objectives of the proposed tests are to estimate the extent of the thermal resource available in flooded mine seams about 50 to 200 m beneath the test site and to estimate the scaling and corrosion potential of the mine waters. The first objective will be addressed by measuring water speed, level, and temperature, as well as flooded-seam geometry. Water chemistry measurements, both in situ and in the laboratory, will address the second objective. The proposed measurements involve rather novel uses of certain standard oceanographic equipment. The two sequential phases of the measurement program are (1) measurements in conjunction with the drilling operation, and (2) continuous in situ measurements. During the first phase, a series of measurements will be conducted in each flooded mine seam intersected by the borehole, with additional measurements being conducted in the open borehole. During the second phase, some of the same measurements will be conducted on a continuous basis in one flooded seam.
