Seismic observations offer the only possibility for remote sensing of physical processes like shock-front spreading, material crushing and ground movement. A better understanding of these processes will help to increase the economy of blasting. We developed a digital seismic monitoring system for research purposes. The system can simultaneously record up to 64 channels with a maximum sampling rate of 31 kHz per channel. A software package for rigorous analysis of blast induced seismic waves has been developed.

From October 1980 through August 1982, surveys were conducted on 19 longwall mining operations to obtain data relative to respirable dust levels associated with particular longwall operations and occupations, to make recommendations for enhancing dust control, and, where applicable, to evaluate the effectiveness of new technology implemented to control dust. The paper summarizes the data collected during these surveys and, where possible, draws conclusions and discusses actions that can be utilized to reduce exposures to respirable coal mine dust on longwall mining operations.
