Analysis And Study On Particle Vibration Damping Of Deep Doal Millisecond Blasting

Millisecond blasting vibration in the deep mine is a very complex and dynamic evolutionary process,such as the complexity of the actual geological conditions, the process of blasting vibration of uncertainty, the problem related to plastic mechanics, mechanics, damage mechanics and fracture mechanics of rock and many other subjects.Firstly, according to the eological features of the deep coal mine blast in the actual application of millisecond blasting impact and effects of the earthquake, and the establishment of model test analysis the main factors of blasting particle vibration.In the test based on the principle of blasting vibration, detailed analysis the blasting vibration test particle in different geological conditions, in the different effect of differential time.In the current explosion of rock damage mechanics and the kinetic theory framework, Analysis the high stress impact of the the blasting crater formation and crater contour control.Based on Millisecond time and Particle blasting vibration theoretical basis, establish the model Millisecond blasting model tests, analysis the impact of Millisecond time to the blasting vibration. Comparative analysis by regression the factors Of particle vibration velocity, acceleration. General discussion. The vibration propagation of Millisecond blasting in the deep coal mine. Based on the analysis and summary of test data explore propagation of Millisecond blasting Particle vibration attenuation and look for a way to Control blasting Vibration.Figure[51] table[32] reference[75]...
