露天采场靠界边坡控制爆破技术实践

Practice of Controlled Blasting Technology of the Slope Close to Border in Open-pit

为确保某露天矿边坡的稳定性,在现状调查和理论分析的基础上,采用预裂爆破技术,根据理论分析和现场试验,确定出适用于不同岩性的爆破参数,最后进行现场施工,取得了较理想的爆破效果,有效保证了高陡边坡的稳定性,为矿区露天边坡的后续施工提供了借鉴经验。

In order to ensure the stability of the slope of a open-pit mine,based on the present situ-ation investigation and theoretical analysis,the pre-splitting blasting technology is adopted,the blasting parameters that are suitable to different lithology are obtained by theoretical analysis and filed test.Based on the above results,the site construction is conducted,the ideal blasting effects is acquired,the stabili-ty of the high and steep slope is ensured.It provides the reference for the further construction of the slope of the open-pit mine.
