爆破地震效应控制技术在锡矿山锑矿的应用

Blasting Seismic Effect Control Technology Applied in the Hikuangshan Antimony Deposits

锡矿山锑矿为安全开采各类残矿和保安矿柱,使用爆破振动记录仪测试了井下爆破振动强度,分析了爆破振动对井下和地表建(构)筑物稳定性影响,预测了爆破振动的安全距离和一次爆破允许的安全装药量,为矿山各类残矿和保安矿柱开采爆破设计提供了依据。

Hikuangshan Twinkling Star Antimony Industry Co. Ltd applies blasting seismic effect contron technology for safety mining various types of remnant ore and security pillar. The contron technology based on blasting vibration recorder tested underground blasting vibration strength,analyzed blasting vibration on the underground and surface construction（ structures） stability,and predicted blasting vibration safe distance and safe loading dose once blasting allows,which provided the blasting design basis for all types of remnant ore mining and security pillar mining.
