尾矿库排水管封堵技术及相关事故处理

Discussion on the drainage pipeline plugging technology in tailings ponds and treatment of related accidents

当尾矿库库底排水管强度不能满足坝体加高的承载要求,且无法进行加固或在使用过程中出现损坏迹象时,均应对其进行封堵。排水管的封堵位置与封堵长度关系到尾矿库的安全运行,必须高度重视,防止留下安全隐患。该文结合某矿山工程事故案例,提出了排水管封堵技术要求以及因排水管承载能力不足导致的事故处理方法,为类似尾矿库工程提供参考。

When the tailings pond bottom drainage pipeline＇s strength does not meet the bearing requirememts of dam height increase and can not be reinforced, or in the process of use a sign of failure appoars, plugging of the pipe- lines is necessary. The place of plugging and the plugging length are connected with the safe operation of the tallings pond, great importance should be attached to prevent potential safety hazard. This paper, based on the similar engineer- ing accident case, puts forward the requirements of drainage pipeline plugging technology and the treatment of resulting accidents from bearing deficiency, providing reference for similar projects,
