摘　　要：采用进路式充填法开采的地下矿山,爆破作业往往在已经充填好的进路附近实施,不可避免会对充填体产生影响。充填体在进路爆破作用下可能形成垮塌,造成充填体支撑强度下降,进而导致矿石贫化,所以在进路式充填法开采的地下矿山进行爆破作业时必须控制爆破振动。针对进路式充填法开采的某地下矿山,研究了充填体爆破振动监测方法,开展了现场爆破振动监测分析工作,得出矿山满足充填体安全的爆破振动值。In underground mines that are exploited by the approach filling method,blasting operations are often carried out near the already filled access,which will inevitably affect the filling.The backfill may collapse under the action of access blasting,resulting in a decrease in the support strength of the backfill,which in turn leads to ore dilution.Therefore,blasting vibration must be controlled during blasting operations in underground mines mined by the access filling method.Aiming at an underground mine excavated by the approach filling method,the method of monitoring the blasting vibration of the filling body is studied,and the field blasting vibration monitoring experiment is carried out,and the safe blasting vibration value of the filling body of the mine is obtained.
