Trailing and reeling cables pose an elevated safety risk in mining operations because a damaged trailing cable can lead to earthing faults and expose workers to direct and indirect electric shock hazards. Under Australian mine safety legislation, these cables require specific design mitigation measures and mandatory periodic testing to ensure ongoing electrical integrity and worker protection. The testing regime encompasses both insulation resistance (IR) testing and earth continuity protection verification, with frequencies determined by the type of mining operation and the applicable state regulations. 在采矿作业中，拖曳和卷绕电缆存在较高的安全风险，因为损坏的拖曳电缆可能导致接地故障，使工人面临直接和间接电击危害。根据澳大利亚矿山安全立法，这些电缆需要特定的设计缓解措施和强制性定期测试，以确保持续的电气完整性和工人保护。测试制度包括绝缘电阻(IR)测试和接地连续性保护验证，测试频率由采矿作业类型和适用的州法规确定。
