Coal Mine Bounce and Roof Fall Research.
1st Symp on Underground Mining NCA/BCR Coal Conf and Expo II 1975 II:104-119
Rock noises were monitored in a deep western Colorado coal mine to study the phenomena of coal mine bounces. Data preceding several bounces of varying magnitude were recorded and analyzed. Techniques were developed to locate and delineate bounce areas within the mine structure and to estimate the stability of individual suspect areas. Analysis of these data indicate that microseismic techniques may be used to establish where coal mine bounces will occur and to anticipate failure.
