Seismic Miner Detection and Location System. Phase 1, Final Report.
NTIS: PB/232-887 Available for Reference At Bureau Libraries :110 pages
The design and field testing of a seismic miner detection and location system (Contract No. H0133112-1) are described. This work was carried out over a period of 3 years. The first 2 1/2 years were sponsored by Continental Oil Company, Although the last period of tests was done as the first part of a 1-year contract with the Bureau of Mines. Laboratory and field experimentation in three different mines under simulated emergency conditions have led to three important results: (1) taps on roof bolts with normally available objects can usually be detected up to horizontal distances of 1,000 ft, (2) the origin of the taps can be located by on-site processing with a small computer, and (3) some predetermination of the approximate location is necessary for a quick and successful rescue. This report also includes preliminary specifications and cost guidelines for construction of a transportable field system capable of matching the performance characteristics of the one used during the field tests.
