Study On Blasting Parameters Optimization And Blasting Vibration Of Hualian Zinc Indium Field In Slope

In recent years, as domestic market impact of large mining, ore prices falling, open-pit mine environment is becoming worse. And with the increase of mining scale, the slope of open-pit mine is higher, the vibration caused by blasting mining slope hazard is more prominent and seriously affected the mine safety production. For the long-term sustainable development of the mining, therefore, we must change the former extensive exploitation pattern into fine mining in order to improve the production efficiency; At the same time researching and analyzing the influence of blasting vibration on slope ensures mine safety production.So the paper combined the hualian zinc and indium open stope’study of blasting parameter optimization and blasting vibration on slope stability influence project as the background, through to the hualian zinc, indium, the home village of stope blasting present situation investigation, put forward the wide hole is apart from the small resistance line design principle of blasting scheme, according to the actual situation of mining and related engineering empirical formula design of blasting parameters and different rows from the combination of blasting scheme; Then use ANSYS/LS-DYNA finite element software to simulate and analyze field test, find the appropriate Union indium zinc Man Zhai stope blasting hole net the optimal program parameters, thereby reducing mining costs, increase economic efficiency mine.In order to obtain more accurate vibration data,surrounding high slope blasting vibration are monitored in hualian zinc indium at the same time. This paper puts forward improvement to verified by means of casting vibration platform vibration effect that combined with indoor and outdoor test.Then blasting vibration attenuation law in the slope of the research carried out by vibration measurement data obtained by the slope of the main vibration frequency of the vibration, and the final analysis Sa’ada Minkowski formula to calculate the vibration propagation regression slope, finalized the edge Poe minimum safety distance, provide the basis for mine safety production.
