Study On The Damage And The Structure Planes Effect Of Rock Mass Blasting

Blasting technology has been widely used in the field of open-pit mining.It removedefficiency of mine production and had negative impact on slope stability at the same time.Inorder to ensure production safety and stability of the slope,the slope damage caused by blastingshould be studied through the combination of theoretical studies and field experiments.Based on vibration data measured in Zha ha nao er opencast coal mine, vibration data werefitted by SaDaoFu tversky formula.Summarize the trend of venue coefficients under repeatedlyblasting, predict rock mass damage;Study the blasting effect when controllability structuresurface position change; Calculate the damage degree based on the acoustic data measuredbefore and after blasting. Summarize the trend that the damage degree increases with the numberof blasting. Put forward the law that the damage degree decreases with increasing distance frommeasuring point to explosive center and the level of dynamite.ANSYS analysis software used tosimulate the blasting and obtained stress distribution of rock mass, compared with the field tests,verified its feasibility.
