摘要
为了保证安太堡露天矿不采区露井联合开采的高效和安全,采用声波测试技术对不采区井工采动损害影响过程中的边坡岩体松弛范围及其分布规律进行研究,分析发现岩体大部分属于破碎—较破碎,稳定性较差,露井联合开采时,不利于边坡稳定,在靠近露天边坡面处采场应采取预裂爆破、光面爆破等保护措施,以减小爆破动载荷对边坡稳定性的影响。
In order to guarantee the safe and efficient exploitation of Reserved-area of Antaibao surface mine, Sonic Wave Test was used to analysis the looseness scope of slope during the process of underground exploitation, it was found that much of the rocks are broken or comparing broken, it is bad for the stability of the slope when combined mining of underground and surface, and some measures should be used to decrease the influence of demolition blast to the slope.
