Under The Effect Of Blasting Vibration Analysis Of Open Pit Slope Injury Law And Weakening Regions

Open pit slope problems threaten production safety; step blasting vibration on theslope stability effects can not be ignored. Based on production, open pit is developing tothe high and steep slope direction, but at the same it inevitably threaten safety of slope,high and steep slope’s step the possibility of blasting vibration hazards are increasing.Therefore, the study opera ting’s blasting vibration injury law and weakening the slopechanges in the region, the slope stability assessment and preventive control measures totake is very important.Based on the test pit Pingzhuang West, obtain and apply on-site blasting vibrationvelocity formula find characteristics of accumulate damage degree of rock mass test andcompare damage degree of fitting, obtain relations among damage degree and the anglebetween direction of blasting energy propagation and slope toward, proposed rule aboutchange of damage degree with angle, and thus determine the dominance of radialfracture and propose methods to repair injury degree.
