Microseismic techniques applied to coal mine safety.
Denver, CO: U.S. Department of the Interior, Bureau of Mines, G0101743, 1974 Mar; :1-208
This report gives the results of a study to determine the feasibility of using transducer arrays, located on the surface or in shallow boreholes, above an active coal mine to detect and locate the sources of microseismic activity that occurs during mining. In general, results were positive. Correlations between rock structure stability and microseismic activity were made.
