Underground coal mining operations in Australia present unique electrical safety challenges that require specialized cable systems and protection strategies. The presence of methane gas, coal dust, confined spaces, and high humidity creates an environment where electrical faults can potentially trigger catastrophic explosions. To mitigate these risks, Australian coal mines employ earth fault limitation systems that restrict fault currents to very low levels, typically 5 amperes (5A) for systems below 4,000 volts. 澳大利亚地下煤矿作业面临独特的电气安全挑战，需要专门的电缆系统和保护策略。甲烷气体、煤尘、狭窄空间和高湿度的存在造就了一个电气故障可能引发灾难性爆炸的环境。为降低这些风险，澳大利亚煤矿采用接地故障限制系统，将故障电流限制在非常低的水平，对于4000伏以下的系统，通常为5安培（5A）。
