Abstract: | Abstract. Resistivity level runs are collected by lowering a current source down one well and measuring the resulting voltage at the
same depth in another well. Mine voids between the wells that contain acid water appear as conductive anomalies on the resulting
apparent resistivity profiles. Resistivity level runs can be collected rapidly and without lowering expensive equipment down
holes of unknown stability. The data can be interpreted on-site, and are relatively insensitive to positioning errors. The
method is well suited to sites where several drill holes have failed to intersect a known mine void. We demonstrated the feasibility
of resistivity level run profiling at an abandoned mine complex in central Pennsylvania, where resistivity level runs were
successfully used to locate haulage ways containing mine water. |
