地下采区开采方法对边坡岩体变形的影响规律

The Law Influencing the Slope Rock Mass Deformation by Underground Mining Methods

在地下与露天复合开采的矿山中，由于露天边坡岩体位于地下采动影响区域内，致使边坡岩体受到两种采动的影响，其中不同的地下采矿方法影 响程度不同。为评价地下开采方法对 边坡岩体的影响，对抚顺西露天北帮边坡变形进行了分析，得出了地下采区不同开采方法对边坡岩体变形的影响规律，为该矿边坡岩体动态分析及类似矿山开采设计提供科学依据。

The slope rock mass of the mines that use the combined underground and open pit mining can be affected by both mining activities as the slope rock mass of the open pit lies in the area affected by the underground mining activity and different underground mining methods can exert different influencies.In order to evaluate the effect of the underground mining methods on the deformation of slope rock mass,an analysis was made on the slope deformation of the north wall of Fushun East Open pit and the law influencing the slope rock mass deformation by various underground mining methods were drawn so as to provide a scientific basis for the dynamic analysis of the mine's slope rock mass and for the mining design of similar mines.The La w Influencing the Slope Rock Mass Defor m ation by Underground Mining Methods Sun Shigu
