摘要
为摸清金川二矿区采场爆破作业对穿沿脉道安全性的影响,采用现场监测的方法,对二矿区1038m水平1盘区3分层进行了爆破振动原位监测。结果表明,二矿区目前采场爆破工艺及参数不会对穿沿脉道造成损伤,处于安全标准范围内。并在上述研究基础上,提出了相应的爆破振动降振措施,为二矿区采场的爆破工艺及参数设计提供了理论依据。
In order to understand the impact of blasting operations on the safety of traverse drifts and ore drifts in the stopes of mining area 2,a in-situ monitoring of blasting vibration was crried out on the third sub-level of panel 3 in mining area 2 by using on--site monitoring method.The result showed that the blasting process and parameters used in the current stopes of mining area 2 will not cause damage to traverse drifts and ore drifts and are within the safety standards.Basing on the study above,measures to re-duce blasting vibration were proposed to provide a theoretical basis.
