The selection of appropriate cables for hand-held mining equipment such as borers, drills, and portable machinery is a critical safety consideration in underground coal mining and general mining operations. Australian and New Zealand Standard AS/NZS 1802 specifies construction and testing requirements for reeling and trailing cables specifically designed for use in underground coal mines, addressing the unique explosion hazards present due to methane gas and coal dust accumulation. Within this standard, different cable types serve distinct purposes, with Type 209 and Type 241 representing two fundamentally different design philosophies for power distribution to mobile equipment. 为手持采矿设备（如钻孔机、钻机和便携式机械）选择合适的电缆是地下煤矿和一般采矿作业中的关键安全考量。澳大利亚和新西兰标准AS/NZS 1802规定了专门设计用于地下煤矿的卷筒和拖拽电缆的结构和测试要求，解决了因甲烷气体和煤尘积聚而存在的独特爆炸危险。在此标准中，不同的电缆类型服务于不同的目的，其中209型和241型代表了向移动设备供电的两种根本不同的设计理念。

AS/NZS 1802:2003 specifically addresses cables for underground coal mining operations, where methane gas hazards and confined space requirements demand exceptional safety standards. The standard mandates electrical symmetry for alternating current supply cables—a critical safety feature that ensures balanced electromagnetic fields within the mining environment. AS/NZS 1802:2003 专门针对井下煤矿作业电缆，鉴于甲烷气体危害和受限空间的要求，该标准对交流供电电缆强制规定了电气对称性——这是确保采矿环境内电磁场平衡的关键安全特性。 AS/NZS 2802:2000 covers cables for surface mining, underground mining (excluding coal), and general industrial applications, with voltage ratings from 1.1/1.1 kV up to 33/33 kV. This standard incorporates Amendment No. 1 (December 2003) and provides specifications for two distinct cable classes based on insulation and sheath thickness. AS/NZS 2802:2000 涵盖露天矿、非煤井下矿及通用工业应用电缆，电压等级从 1.1/1.1 kV 至 33/33 kV。该标准包含2003年12月的第1号修订版，并根据绝缘和护套厚度提供两种不同电缆等级的规格。
