降雨条件下尾矿库稳定性影响研究

Study on the Impact of Tailings Reservoir Stability under Rainfall

尾矿库为矿山企业的配套设施,其安全运行与企业的生产、建设息息相关,而且尾矿库的安全运行将影响下游村庄的生命财产安全。本文以云南省某尾矿库为研究对象,将模拟软件、实地考察与室内土工试验所获得的相关物理力学参数为基础,在遭遇设计最大降雨的条件下对尾矿库坝体稳定性进行分析。结果发现,该尾矿库的坝体稳定性在坝高增加的情况下符合规范要求,可保持稳定;在降雨条件下,其坝体的稳定性随之降低。

Tailings reservoir is a supporting facility for mining enterprises,its safe operation is closely related to the production and construction of enterprises,and the safe operation of tailings reservoir will affect the safety of life and property of downstream villages.Taking a tailings pond in Yunnan Province as a research object,based on simulation software,field investigations and related physical and mechanical parameters obtained from indoor geotechnical tests,this paper analyzes the stability of the tailings pond dam under the conditions of maximum designed rainfall.It is found that the stability of the dam body of the tailings reservoir meets the requirements of the code when the dam height increases,and it can maintain stability;under rainfall conditions,the stability of the dam body decreases.
