摘要
边坡稳定与否是露天矿山安全生产的关键问题之一。本文应用灰色理论方法,建立了灰色预测模型,并以变形实测资料为基础,回归求出相关参数,并对边坡预测模型的误差进行了拟合分析,其拟合精度非常高;然后对后续变形进行了预测,预测结果表明,随着露天开采的继续,边坡变形会持续增大,由此将对边坡安全产生严重的影响,因此,需要对边坡稳定采区控制措施,同时强化预警体系建设,以便确保安全生产。
Slope stability is a key factor in safety production of open-pit, then, the method of grey prediction is appfiod in this paper, and the relevant parametem are determined by regression with establishing grey prediction model and basing on actual measurement data of deformation, and fitting analysis is used in error of slope prediction model with high fitting accuracy; then the follow-up deformation is predicted, and the results of prediction show that the deformation would eontlnue to increase with open- casting work, and it would generate a severe influence on safety of slope stability, thus, mining area control measurements, as well as building of early warning system, should be required and strengthened to ensure safety of production.
