The correct termination of the central pilot core in mining trailing and reeling cables represents a critical safety procedure that ensures the integrity of the earth continuity monitoring circuit. This monitoring system provides continuous verification that the equipment grounding conductor (EGC) remains intact, protecting personnel from potentially fatal electric shock hazards in the event of a phase-to-ground fault while the earth path is compromised. Improper termination of the pilot core can render the entire earth continuity protection system ineffective, creating a dangerous condition where ground faults may not be detected. 中文说明：采矿拖缆和卷缆中中心引导芯的正确终接是确保接地连续性监控电路完整性的关键安全程序。该监控系统持续验证设备接地导体（EGC）保持完好，在接地路径受损时发生相对地故障的情况下保护人员免受潜在致命电击危险。引导芯的不正确终接可能使整个接地连续性保护系统失效，造成可能无法检测到接地故障的危险状况。

AS/NZS 1802 is the Australian and New Zealand standard that specifies construction and testing requirements for reeling and trailing cables specifically designed for use in underground coal mines.1 These cables are engineered to withstand the harsh environmental conditions found in mining operations, including mechanical stress, moisture, and potential exposure to hazardous atmospheres. The standard aligns with AS/NZS 2802 for cables developed to meet the special requirements of the surface mining industry and introduces critical safety features including earth fault screens and central pilot cores.
