Acid Mine Drainage represents one of the most challenging environmental conditions for electrical infrastructure in mining operations. AMD occurs when sulfide minerals, particularly pyrite, are exposed to oxygen and water during mining activities, producing sulfuric acid through oxidation reactions. According to research from the United States Geological Survey, AMD environments typically exhibit pH levels ranging from 2 to 4, with extreme cases documented as low as pH 0.5 to 0.9 at facilities such as the Richmond Mine in California. 酸性矿井排水（AMD）是采矿作业中电气基础设施面临的最具挑战性的环境条件之一。当硫化矿物（特别是黄铁矿）在采矿活动中暴露于氧气和水中时，通过氧化反应产生硫酸，从而形成AMD。
