摘　　要：对于采煤机金属屏蔽软电缆,其地线芯和屏蔽层的并联最大接地电阻是重要性能指标之一。通过理论分析和试验验证,建立了金属编织屏蔽层电阻的计算方法,对地线芯和屏蔽层的并联接地电阻进行了计算。在满足并联接地电阻要求的前提下,对屏蔽层结构进行了优化设计。The maxium parallel grounding resistance of metal shield and ground core was one of the most important performance indicator for metal shield cables used with coal cutters. The resistance calculation method of woven metal shielding layer was established by theoretical analysis and experimental verification. The parallel grounding resistance of metal shield and ground core was calculated. Shielding layer structure was optimal designed based on parallel grounding resistance.
