青海某石灰岩矿区边坡稳定性分析与评价

Analysis and Evaluation of Slope Stability in a Limestone Mining Area of Qinghai

随着经济的飞速发展,我国的矿山行业也不断发展起来,而矿山开采过程中的工程问题屡见不鲜。大型露天矿山开采时,其边坡的稳定性关系到工程能否正常进行,所以边坡稳定性分析是矿山开采工程中必不可少的环节之一。文章以青海西部某制碱石灰岩矿山为研究对象,依据国家相关法律规定和技术标准,采用极限平衡法对其东部、中部、西部的边坡稳定性进行了分析和评价,并提出了防治建议,以期为类似石灰岩矿山开采提供工程地质基础性资料和技术支撑,也有益于矿山的开采工作设计。

With the rapid development of economy,China’s mining industry is also developing,and engineering issues in the mining process are common.When large-scale open-pit mine is mined,slope stability is related to whether the project can be carried out normally,so slope stability analysis is one of the indispensable links in mining engineering.Taking a alkali limestone mine in western Qinghai as the research object,and according to the relevant national laws and regulations and technical standards,this paper analyzes and evaluates the stability of the eastern,central and western slopes of the mine by using the method of limit equilibrium,and puts forward some suggestions for prevention and control,so as to provide engineering geological basic data and technical support for similar limestone mining,which is also beneficial to the design of mining work.
