Abstract
A microseismic roof fall warning system was field tested in western and eastern coal mines in the United States to better define the capabilities and limitations of the microseismic method in predicting roof fall. Microseismic event and energy type data were obtained and documented for 23 coal mine roof falls. Field test results indicate that both the microseismic event and energy methods, as applied, have a high probability for successful application in a commercially practical roof fall warning system. Volume II summarizes the data collected.
