Abstract


Blasting is the broken rock means the most important in the rock slope excavation process . Rock Blasting A force is extremely complex process . Limitations due to the complexity of the rock mass properties , blasting variability and measurement means , the lack of adequate understanding of rock mass blasting excavation . At the same time , the excavation blasting construction has a great impact on the stability of the slope . Therefore, the study of high slope excavation blasting technology , with a strong theoretical and practical significance . Slope blasting vibration system test analysis to explore the blasting vibration wave propagation , combined with Laxiwa Canyon Alpine steep Highland stress on practical engineering , research and exploration for the specific project pre- split blasting and deep bench blasting optimization of parameters and blasting Network , a the practical the damping vibration reduction blasting measures . Mainly to obtain the following results : (1) determine the the Laxiwa high slope deep hole pre-splitting blasting parameters bench blasting parameters ; (2) the slope excavation blasting Blasting Network ; (3) analysis of the slope of the deep hole bench blasting scale ; ( 4 ) to determine the size of the deep-hole bench blasting excavation ; (5) a deep hole bench blasting safety control standards . The results show that the blasting vibration can be controlled , only to realize that the laws of burst Discovering propagation and attenuation , to take a series of charge cloth hole control measures , can be achieved to reduce vibration and improve the blasting effect , can help the high slope stability of excavation blasting effect .
