Study On Monitoring Of Blasting Vibration And Damage Control In Hongtoushan Copper Mine

Blasting vibration damage is one of the important against blast, frequent underground structures caused by blasting or blasting will damage (breakage, collapse, fall, etc), caused significant harm to the production and workers’ life security. Harm of blasting vibration control has been the major research subjects of blasting safety technique at home and abroad. Hongtoushan copper zinc mine mining depth over km, to pressure situation more obviously, due to blasting induced of roadway damage on production caused serious effect, this based Shang made on red through mountain blasting vibration signal analysis and against control research topics, to-707Middle35mining, and29mining in the deep hole large blasting monitoring signal for relying on, in predecessors research of based Shang for following discussion:(1) Using Association analysis, discussion on blasting parameters of blasting vibration velocity and the relevance of the analysis of blasting parameters of influence of blasting vibration intensity levels, provide the basis for controlled blasting hazards, provide guidance for optimization of blasting parameters;(2) Experience formula to predict the propagation of blasting vibration and analysis taking into account influence of elevation factors, fitting of best prediction model finds the propagation of blast vibration;(3) The effectiveness of treatment of non-stationary signals using Wavelet transform, from the energy point of blasting vibration signal analysis to study ground zero margin, direction of propagation, the total dose effects on the distribution of vibration energy, further clarifying the propagation characteristics of blasting vibration signal(4) Through the analysis and discussion of possible safety criterion of blasting vibration and analysis of deep-hole blasting in hongtoushan peripheral effects of roadway structure. Validated through field investigation, analysis of blasting parameters of hongtoushan copper-zinc mine of rationality, rationality and make comments; (5) From the perspective of poor micro-vibration reduction to get the best millisecond time;...
