摘要:

为了减少矿柱的损失,在三山岛金矿直属矿区内,采用基坑开挖的方式对地表以上+10 m至地下-2.0 m的矿体进行回采。受现场工业厂房布置限制,并考虑加快施工进度、降低生产成本等方面因素,爆破方式采用中深孔松动控制爆破技术。为了最大限度地降低爆破震动对周边环境的影响,首先对基坑轮廓先进行预裂爆破,再进行中深孔松动控制主爆破。通过对2种控制爆破的爆破参数进行详细确定,分析爆破效果,阐述了爆破方案选择、爆破参数优化、起爆网路的设计和爆破安全校核与防护,为类似工程设计提供参考。

关键词: 基坑开挖, 预裂爆破, 中深孔松动控制爆破, 微差爆破, 爆破网路

Abstract:

In order to reduce the loss of safety pillar,using pit excavation method to recovery the orebody from surface 10 m to -2.0 m within the immediate mining area of the Sanshandao gold mine.Because subject to site layout of the plant and taking account of speeding up the construction schedule and reducing the production cost,we choose the blast pattern of long-hole shock controlled blasting.To maximize the reduction of blasting vibration on the surrounding environment,proposed the program of pre-splitting blasting on pit outline first,main blast of longhole shock controlled blasting in deep hole later.In this paper,parameters of two controlled blasting method is determined in detail,blasting effect is analyzed.Elaborate on blasting program choosing,blasting parameter optimization,initiation network design and security checking and protection,provides a reference for similar projects.

Key words: Pit excavation, Pre-splitting blasting, Long-hole shock controlled blasting, Millisecond blasting, Blasting network
