矿山高陡边坡崩塌灾害演化的成因分析

Cause analysis of landslip disaster evolvement of high hilly slope in mine

结合铜川市区自然地理地貌条件,分析了市区所属黄土坡地、矿区高陡山体边坡下煤层开采引发的环境岩土工程问题。对矿区高陡山体边坡崩塌环境灾害的影响因素进行了分类分析;对矿区开采与地表移动变形和高边坡崩塌灾害演化形成的机理进行了分析。结合实例,应用 CEPDF 程序模拟计算,研究结果对于铜川市区条件下高陡山体边坡灾害防治有一定参考价值。

According to natural geographical condition of Tongchuan City,the mining-induced environment rock mass engineering problems under loess slope or high hilly slope in Tongchuan coalmine diggings,are analyzed.And then a classified analysis about the affect factors of landslip disaster in high hilly slope is carried out.The evolvement mechanism of landslip disaster and ground subsidence due to construction digging or mining is also analyzed.Using CEPDF to simulate a typical example,the research results provide some referential value for predicting or controlling the hilly slope disaster in Tongchuan City.
