INTRODUCTION <br />VME Nitro-Consult Inc., acting as the blast vibration consultant <br />to GEC Minerals, Inc., monitored the 4:30 P.M. coal over-burden <br />shot on Wednesday Jenuery 28, 1981. Mine location is approximately <br />6 miles south of Florence, Colorado. <br />Six VME manufactured seismographs were positioned within a 1000 <br />ft. radius of the blast. Five of the six instruments were placed <br />on the adjoining Dorchester Mine property at 'criticnl' points <br />as defined by Dorchester personnel. <br />Vibration data were obtained at the six locations, and a regression <br />analysis was performed using the subject data obtained. Tl~e data <br />appear at another section in this report - as do the conclusions <br />which result from the data and their study. <br />,I ._ .i <br />
