- 摘要:
- 露天矿深部资源开采因受到剥采比等因素的制约需要转为井工矿开采；从采掘空间位置分布关系来看，边坡体位于地下采动影响域内，由此造成了两种采动效应的相互作用，并构成复合叠加效应，使得边坡稳定性受到严重影响，一旦产生滑坡将严重影响周边环境的安全或诱发次生灾害。以某矿的开采工程实践为背景，针对地下开采作用下山体与露天边坡的稳定性进行了研究，系统分析了露天坡和山峰外侧边坡的稳定性，并对滑坡可能产生的后果及其次生灾害进行了分析，从而为矿山安全生产和防控提供了决策依据
- Abstract:
- The mining of deep resource in the open-pit mine restricted by the stripping ratio factors should turn to underground mining. From the view of spatial distribution relationship in mining, the slope body is located in the influence domain of underground mining. It leads to the interaction between two types of mining effect, and forms a compound superposition effect. The slope stability is seriously affected, and once the slope sliding happens, it will seriously affect the safety of surrounding environment or induce secondary disasters. Based on a mining engineering practice, the stability of mountain body and open-pit slope under the effect of underground mining was studied, and the stability of open-pit slope and mountain peak lateral slope was systematically analyzed. The possible consequences of landslide and its secondary disasters were analyzed, which provides a decision-making basis for the mine production safety and safety control.
