摘要
为了满足煤矿安全生产的需要,必须对矿井瓦斯进行抽放。传统抽放管路都是使用钢管,其重量大、安全性差、不易安装。矿用聚乙烯管材具有重量轻、防静电、阻燃、碰撞不起火花、耐腐蚀、耐磨损、易于安装等特点,使用寿命可达到50 a,代表着煤矿瓦斯抽放管道的发展趋势。
In order to meet the needs of the coal mine production safety,gas drainage must be carried out.Steel pipes are used in the traditional pipeline,they have large weight,poor security,hard to install.The mine polyethylene pipes have a light weight,anti-static,flame-retardant,affording sparks crash,corrosion resistance,wear-resistant,easy to install,and other characteristics,the useful life of 50 years,represent the development trend of gas drainage pipelines in coal mines.
