Blasting vibration is a key factor to induce rock mass instability in underground mines,it is important to master the propagation characteristics of blasting vibration,and effectively control the damage of blasting vibration,which is meaningful to safe and efficient production.In order to study the influence of medium-long hole blasting on the structures around the stope in Wanjiawu mining area of Jinshan gold mine,the blasting vibration test was carried out.The collected blasting vibration signals are comprehensively analyzed from the aspects of blasting vibration intensity,frequency,and time,and the propagation model of blasting vibration intensity and frequency in the mining area is established.On this basis,the vibration influence range of medium-long hole blasting is determined,the calculation method of the maximum allowable single dose was obtained,and the micro-difference initiation time between rows was optimized.The parameters of medium-long hole blasting are more reasonable,and ensure the stability of the rock mass and other structures around the stope,so as to realize the green,safe,and efficient production goal of the mine.
