| 摘 要： | 在矿产资源开发过程中，露天开采转为地下开采后，露天边坡受地下采动影响，由于两种采动影响部分重叠，造成两种采动效应相互作用，构成复合叠加效应，使得上覆岩体变形机制更加复杂、变形波及范围广。以北京某矿的开采工程实际为背景，研究了复杂的环境工程地质条件下露天转地下开采过程中地表变形的动态演变规律、滑移机制和破坏区的界定等内容，并得出了其开采过程中的动态破坏范围及其移动参数的演变特点，从而为矿山安全生产和安全防控提供了决策依据。

| Abstract: | In the process of mineral resources development, the mining of deep resource in the open-pit mine restricted by the stripping ratio factors should turn to underground mining. Open-pit mining is located in the underground mining influence domain. This causes part of the two mining influence domain overlapping, of the two types mining effect, thus, it constitutes a compound superposition effect, and makes the overlying rock mass deformation mechanism more complicated and the deformation spread widely. This paper takes a mining engineering practice in Beijing as the background, to study the Dynamic evolution law, the sliding mechanism and the definition of damage zone of the surface deformation in the process of the excavation from open-pit into underground mine under complex conditions of environmental engineering geology. It also summarizes the evolution characteristics of dynamic damage range and movement parameters in the mining process, thus provides a decision-making basis for the mine safety production and safety control. |
