煤矿非金属管道系统失效原因分析及对策研究

Cause Analysis and Countermeasure Research on Failure of Non-Metallic Pipeline System in Coal Mine

摘要: 非金属管道系统断路是影响非金属瓦斯抽采管道系统失效原因之一，通过对近年来煤矿非金属管道事故的梳理，从原材料的生产、产品的选型、后期安装使用及维护等方面进行总结归纳，制约煤矿井下非金属管道安全使用的主要矛盾是非金属管道在抽采瓦斯过程中产生火花形成断路、产品选型不匹配等。总结出合理的选型，严谨的设计、相对应的法规政策规范及科学的管理和使用可有效地减少煤矿非金属瓦斯管路系统事故的发生，为解决煤矿井下非金属管道系统的安全使用提供参考。

Abstract: The open circuit of non-metallic pipeline system is one of the reasons that affect the failure of non-metallic gas drainage pipeline system. Through combing the accidents of non-metallic pipeline in coal mines in recent years, this paper summarizes the production of raw materials, the selection of products, the later installation and use, and the maintenance. The main contradiction restricting the safe use of non-metallic pipelines in coal mines is that non-metallic pipelines produce sparks in the process of gas drainage to form open circuit and product selection does not match. It is concluded that reasonable selection, rigorous design, corresponding laws and regulations, scientific management and use can effectively reduce the occurrence of non-metallic gas pipeline system accidents in coal mines, and provide reference for solving the safe use of non-metallic pipeline system in coal mines.
