Abstract
The objective of this study is to evaluate an instrumentation and field monitoring program designed to record and monitor surface blasting effects on underground coal mine openings. Potential damage criteria and guidelines were developed by quantifying the relationship between identifying the nature and degree of underground vibrations and damage produced in a mine on the underground structure. To predict the characteristics of underground vibrations occurring from a surface blast, the propagation relations of underground vibrations from surface blasting were established through the use of measuring devices. Part of the study provides an approach to the design of an instrumentation and field monitoring program for use in investigating the damage criteria of surface blasting on underground coal mine openings.
