Vertical Seismic Profiling (VSP) Surveys to Detect Old Mine Works at the Sterling Mining Company, Carroll Hollow Mine, Jefferson County, Ohio

摘要

Two vertical seismic profiling (VSP) survey projects were conducted at the Sterling Mining Company (SMC) property to detect the old abandoned Sterling Mine works, which closed in 1962. The first survey was conducted on May 24, 2005 in an open hole filled with water. The hole location was supposed to be within 80 ft of the projected old mine works boundary. A total of six far-offset VSP data were collected. However, the processed data did not provide conclusive evidence that clearly showed anomalous signals that could be interpreted to be associated with the detection of old mine workings. After the surface seismic survey program was completed and verified by drilling and hole-to-hole tomography surveys, it became apparent that the VSP Hole No. 1 was not within the proposed 80-ft distance to the old mine works. Instead, the boundary of the old mine works was found to be about 300 ft further south.
