【摘要】：充填管道的稳定性是充填系统安全运行的关键,而充填管道堵塞是料浆输送过程中发生最为频繁的事故。为合理分析充填管道堵塞的直接原因和间接原因,在综合分析充填管道堵塞事故的基础上,运用安全系统工程中的事故树分析法,建立了充填管道堵塞事故树模型。通过分析和计算事故树的最小割集、最小径集和基本事件的结构重要度,找出了导致充填管道堵塞的主要因素。结果表明:导致充填管道堵塞的路径共有落入异物、格筛破损、管道内径不当等22条,预防充填管道堵塞的途径共有合理控制料浆配比、规范相关设计、消除管理缺陷等4种;水泥用量不合理、料浆配比不合理、弯管较多等16个因素是导致充填管道堵塞的最重要因素。事故树分析法能对导致充填管道堵塞的各种因素及逻辑关系做出全面的阐述,并根据结构重要度提出针对性的防治措施,为充填管道的安全管理提供了可靠的参考依据。
[Abstract]:The stability of the filling pipeline is the key to the safe operation of the filling system, and the plugging of the filling pipeline is the most frequent accident in the course of slurry transportation. Based on the comprehensive analysis of filling pipeline blockage accidents, the fault tree model of filling pipeline blockage is established by using the accident tree analysis method in safety system engineering, and the minimum cut set of the accident tree is analyzed and calculated. The structural importance of the minimum path set and basic events has been found out, and the main factors leading to the blockage of the filling pipeline have been found. The results show that the paths leading to the blockage of the filling pipeline fall into foreign bodies altogether, the screen is damaged, the inner diameter of the pipeline is improper, and so on. There are four ways to prevent filling pipe plugging, such as reasonable control of slurry ratio, standardization of relevant design, elimination of management defects, unreasonable cement dosage, unreasonable slurry ratio, and so on. Sixteen factors, such as more bends and so on, are the most important factors leading to the blockage of filling pipes. The accident tree analysis method can give a comprehensive description of the various factors and logical relationships that lead to the blockage of filling pipes. According to the importance of the structure, the prevention and cure measures are put forward, which provides a reliable reference for the safety management of the filling pipeline.
