摘要
为保证露天转地下平稳过渡,需对-30 m水平挂帮矿进行开采,而西南边帮的稳定确保挂帮矿的顺利开采,因此基于杏山铁矿复杂的地质条件和矿区在露天转地下条件,对西南帮边坡变形破坏规律进行了分析。在分析西南边坡变形破坏规律的过程中,主要运用灰色系统理论建立了杏山铁矿GM(1,1)预测模型,应用该预测模型对杏山铁矿边坡实际监测数据进行了分析,并将其结果与现场监测数据进行了对比分析,说明其变化趋势与监测结果基本一致,验证了GM(1,1)预测模型的可靠性,为模型后期的预测提供了理论依据。
In order to make the stable transition of open-pit mine to underground mining, - 30 m hanging-wall ore needs to be explored, and the stability of southwest boundary will ensure the smooth mining of hanging-wall ore. Based on the complex geological conditions and condition of open-pit mine transiting to underground mine of Xingshan iron mine, the deformation and destroy regulation of southwest boundary stope is analyzed. During the process of analyzing the deformation and destroy regulation, grey system theory is mainly adopted to construct predicting model-GM ( 1,1 ) of Xingshan iron mine. The monitoring data are analyzed by the GM (1,1) model, and the resuits calculated by the model are compared to the pratcial monitoring data. Through the comparative analysis, the changing tendency analyzed by GM ( 1,1 ) model is consistent to the practical monitored results, which demonstrates the reliability of GM ( 1,1 ) , and provides theory basis for the latter prediction of the model.
