安家岭露天矿南帮边坡不稳定区域防治措施

Prevention measures of south slope instability region in Anjialing Open-pit Mine

安家岭露天矿通过开展边坡年度稳定性评价工作,对稳定性不足区域提出治理措施,并结合下1年度生产计划对采矿方案进行调整。安家岭露天矿采矿主要调整南帮逆断层影响区域,通过提前掏槽开采—快速内排压脚,使逆断层影响区域满足边坡安全;快速内排压脚后并对原运煤系统进行了调整,可以有效缩短运煤路线,在保证安全基础上取得可观的经济效益。

Through developing slope stability evaluation work, the article presents the controlled measures on the instability region and adjusts the mining scheme combining with the production plans next year. The mine mainly adjusts south slope reverse fault area, and advances cut mining-- fast internal dump to ensure slope safe. After fast internal dump, the mine adjusts the original coal conveying system to effectively shorten coal transportation line, which obtains good economic benefits on the basis of ensuring safety.
