浅析低烟无卤技术在煤矿用电缆的应用

Application of Low Smoke and Halogen-Free Technology in Coal Mine Cables

摘要: 根据《煤矿安全规程》的规定，煤矿用电缆必须具有阻燃性，为达到这一要求，电缆大多添加卤素阻燃剂。但在添加阻燃剂的同时并未考虑燃烧时所产生的卤酸气体和发烟量的大小，造成煤矿火灾事故中人员的“二次伤害”。本文通过阐述国内外低烟无卤电缆的发展情况，针对我国煤矿用电缆的现状，对多种低烟无卤电缆进行对比试验，通过数据分析和对比，阐述了低烟无卤电缆在煤矿井下应用的可行性，为煤矿低烟无卤电缆的安全使用提供参考和技术依据。

Abstract: According to the “Safety Regulations for Coal Mines”, the cables used in coal mines must be flame retardant. To meet this requirement, most of the cables are halogen flame retardants. However, when adding flame retardant, the amount of halogen gas and smoke produced during combustion is not taken into account, resulting in “secondary injury” of personnel in coal mine fire accidents. This paper describes the development of low-smoke and halogen-free cables at home and abroad, and compares the current status of China's coal mine cables with a variety of low-smoke and low-halogen-free cables. Through data analysis and comparison, the feasibility of low-smoke hal-ogen-free cable application in coal mines is expounded, which provides reference and technical basis for the safe use of low-smoke and halogen-free cables in coal mines.
