Assessment of Blasting Vibrations from Surface Mine Blasting in Peabody's Universal Mine, Blanford, IN

摘要

The report is an assessment of blasting vibrations in the area around Blanford, Indiana. These vibrations result from production blasting in the nearby Peabody Universal surface coal mine. Questions examined in the preliminary study are: Does a real physical problem exist resulting in the abnormal community response. Are the blast vibrations abnormal in frequency character, amplitude or duration; If so, hypothisize the cause(s) including the possibility of the influence of existing abandoned underground mine workings under and around Blanford; Provide recommendations for follow-on work to better understand the problem and assist in establishing procedures to minimize it.
