• Description:
  As part of the Bureau of Mines program to develop criteria for the proximity of surface blasting to underground mines, field studies were performed during blasting operations for strip coal mining above room-and-pillar workings at Jenny Mine in eastern Kentucky. Measurements and observations were made to identify physical changes in the mine. No change in the frequency of roof falls or any other indications of apparent damage was noted. Recordings of blast- induced vibrations were made using sensors on the roof and floor of the underground mine and at the ground surface. A maximum particle velocity of 17.5 Inches per second was recorded on the mine roof. The vibration data were analyzed and comparisons were made between roof vibration levels and those recorded on the mine floor and at the ground surface. Results are compared with previous blast vibration studies. Recommendations are made for further study toward developing criteria. [Description provided by NIOSH]
