Abstract
Cooperative research between U.S Bureau of Mines and Colorado school of Mines investigators has resulted in the development of a seismic system to evaluate roof stability in underground mines. After a review of geologic, geophysical, and rock mechanics data from four mines, a field site was selected near Green River, Wyoming. An instrumentation plan was developed for monitoring strata movement, pillar stresses, and changes in material properties during both development and retreat mining. This program was designed to complement seismic data with a precise picture of strata movement, fracturing, and stress distributions. Field testing of this integrated system has been completed.
