underground mining trailing cable

27 Min Read
Ghana's mechanized underground gold mines — Obuasi (AngloGold Ashanti), Tarkwa/Damang (Gold Fields), Akyem (Newmont), Bibiani (Asante Gold), Chirano (Kinross) — operate fleets of Sandvik continuous miners, bolters, and load-haul-dump (LHD) machines that were specified and commissioned by Australian contract mining companies. The OEM trailing cables on these machines are Olex (Nexans Olex) Type 241 — manufactured in Australia to AS/NZS 1802, the Australian standard for mining trailing cables. But Olex does not manufacture in Africa, has no West African distribution, and ships from Melbourne with a 18–26 week total procurement cycle. When a 200-meter trailing cable is crushed by a roof fall, sliced by a shuttle car, or degraded by months of dragging through acidic Birimian groundwater, the mine cannot wait half a year for a replacement. The mine needs an equivalent trailing cable that matches the AS/NZS 1802 Type 241 construction, meets Sandvik's OEM specifications, satisfies Ghana Minerals Commission safety requirements, and can be delivered in 8–12 weeks. This guide provides the engineering framework for that replacement.

Underground LHD (Load-Haul-Dump) loaders — also called scooptrams — rely on a flexible trailing cable that is continuously reeled and unreeled as the machine travels between muck piles and ore passes. The cable must survive thousands of reeling cycles, simultaneous tensile and torsional loads, crushing from rock debris, and exposure to water, oil, and abrasive dust. Two cable families dominate this niche: the Nexans TORERO® series (type designation NSHTOEU) and the more generic NSSHÖU heavy-duty rubber cable. 井下 LHD（铲运机/Scooptram）依靠持续收放的柔性拖曳电缆供电。该电缆需承受数千次卷绕循环、拉伸与扭转同时作用的载荷、岩石碾压以及水、油与粉尘侵蚀。两大系列电缆在此领域占据主导：Nexans TORERO®（型号 NSHTOEU）与通用的 NSSHÖU 重型橡套电缆。 This article explains the structural, electrical, and mechanical differences between the two, examines why many OEMs and mine operators specify the TORERO type for LHD duty, and introduces Feichun's comparable alternative manufactured in Anhui, China. 本文将阐明二者在结构、电气与机械性能上的差异，分析 OEM 与矿方为何为 LHD 工况指定 TORERO 型，并介绍飞纯在安徽制造的同等替代方案。

What is Type 14 BS 6708 Trailing Cable?

BS 6708 Type 14 Trailing Cable represents a specialized engineering solution within the British Standard family of mining cables, specifically designed for power distribution to excavating and crushing machines in underground coal mines and surface quarrying operations. This cable type features a unique configuration that balances electromagnetic protection with cost efficiency and simplified installation. 🔑 Critical Distinguishing Feature Unlike Type 11 cables where all cores are screened, Type 14 features screened phase cores only, with the pilot core and earth core intentionally left unscreened. This design choice provides specific advantages in fault current handling and cable weight optimization while maintaining essential EMI protection for power conductors. According to BS 6708:1998 classification, Type 14 belongs to the family of non-armoured cables with individually metallic screened cores rated at 640/1100 V, specifically designated for use with coalface cutters and similar mining machinery. The standard encompasses Types 7, 7M, 7S, 11, 14, and 16, each with distinct screening configurations optimized for specific operational requirements.
