金川二矿区井下开采爆破振动监测与分析

Monitoring and Analysis of Blasting Vibration in Underground Mining in Jinchuan No.2 Mining Area

井下爆破振动通常会对巷道围岩及支护体产生破坏作用,本文通过对二矿区爆破振动进行监测,分析爆破振动波对巷道产生的不利影响,并用现场监测和理论分析二矿区爆破振动波的衰减规律,在此基础上采取合理的降振措施和安全措施,降低爆破振动对巷道及充填体稳定性的危害,为二矿区安全高效回采提供相关的依据。

Underground blasting vibration usually destroys the surrounding rock and supporting facilities in roadway.Through the monitoring of blasting vibration in the second mining area,this article analyzes the adverse influences on roadway imposed by blasting vibration.This article also proposes to analyze the attenuation rule of blasting vibration waves in the second mining area by using field monitoring and related theory,and to take reasonable vibration reducing measures and safety measures to reduce vibration's damage to roadway and the stability of flling body,so as to provide basis for high-efficiency stopping in the second mining area.
