摘　　要：在各类矿产资源的开采过程中，有许多矿区属于地下与露天复合开采情况。依据采区的空间对应关系，两种采动影响域中的一部分相互重叠，致使其采动效应相互作用和相互叠加，从而组成一个复合动态系统。该文在实例分析的基础上，主要研究地下采动对边坡岩体变形的影响特点与规律，并结合采矿特点进行分析，从中探索地下与露天复合采动体系中边坡岩体变形与破坏机理，以便为此类矿山后续采矿设计及安全生产提供理论依据。In the course of exploitation for various kinds of mineral resources, many mine areas belong to the composite underground and strip expoitation. In accordance with the spatial corresponding relation, part of the two exploited influenc- ing scopes will be superimposed with each other, that enables its exploitation effect being interacted and mutually overlaid, thereby a composite dynamic system is formed. On the basis of analyzing the case histories, the paper mainly studies the influencing characteristics and regularity of the slope rock mass deformation resulted from underground exploitation, and analysis has been made in combination with the mining features, therein to explore the slope rock mass deformation and destruction mechanism in the composite underground and strip mining system, so as to propose a theoretical basis of successive mining design and safe production for such king of mines.
