Damage Of The Buildings On Underground Mining Blasting Vibration

Along with the development of domestic mining enterprises, the amount of undergroundproduction is increasing. In daily a large percentage of production operation link blasting dueto carelessness to ignore the harm of blasting vibration, buildings (structures) lead to grounddamage, the economic losses of civil disputes, in society cause negative influence, and theserious influence on the related enterprise normal production life order.This paper the application of vibration instruments to blasting vibration theory and technologyas the foundation. First of all, the use of safety system engineering in advance of the risk analysismethod. The method of fault tree of mining area of influence of the blasting vibration in thebuildings of the qualitative and quantitative analysis. Evaluation management level and calculatethe influence the stability of the building to the ground of minimum cut set. Find out the basicevent of the fault tree of the structure importance, used to guide the construction processmonitoring and adjust the blasting parameters and find the blasting vibration control method for thesecurity system to provide the theory basis. To guide the rational choice of the blasting vibrationwave monitoring programme. Secondly, in the blasting vibration TOPBOX instruments used tocollect the data of the blasting vibration, and then use mathematical software of origin to collect theblasting vibration data regression analysis, calculates the K and α value of SA sadowsky formula,and Correction SA sadowsky formula. Another formula calculation in established of the distanceand single period under the charge of the vibration velocity, V. The use of the blasting vibrationacquisition of the vibration velocity instrument concludes that the relative error of scope, proveregression formula can used to guide the construction site. Using the software of vibration velocityV origin and proportion of linear fitting quantity q, from the fitting map of the blasting vibrationwave spread out decay laws. Finally the vibration monitoring instruments from collection ofparticles peak frequency and vibration velocity two aspects of the data in the course of productionmay affect the safety of the building of the ground are evaluated. With linear regression SAsadowsky formula reference, and guide the subsequent mining face in the process of blastingconstruction of blasting parameters adjustment, to ensure the safety of the provisions in thebuilding and vibrating velocity in frequency.
