摘要
通过对焦山矿爆破震动的监测分析,总结了影响爆破震动的主要因素。在此基础上,总结介绍了在露天矿爆破设计和施工时,降低爆破震动效应的几种技术措施。如采用微差爆破技术,限制微差爆破最大一段炸药量,选择松动爆破和加强松动爆破,合理确定最小抵抗线方向,等。
By monitoring and analysis of explosion seismic of Jiaoshan mine, the main factors of explosion seismic were summarized, based on which, several measures to lower the seismic effect in explosion design and construction of open pit were introduced as applying millisecond blasting technology, limiting dynamite quantity of the max section, chosing and strengthening loose blasting, and seting a reasonable minimum burden direction, etc.
