Coal and mineral resources

The coal and mineral industries—including underground mines, open-pit mines, coal preparation plants, coking‑plant support facilities, and mine‑site logistics—exhibit core characteristics such as high dust levels, high humidity, elevated methane concentrations, severe corrosion, heavy mechanical impacts, confined spaces, explosion‑proof requirements, continuous production, and extreme power‑supply conditions. Transformer solutions must be designed around eight key dimensions: intrinsic safety, explosion‑proof and corrosion‑resistant construction, impact and heavy‑load resistance, high reliability and redundancy, dust‑ and moisture‑proofing, intelligent operation and maintenance, emergency‑response support, and compliance with applicable standards. These solutions cover all scenarios, including underground power supply, open‑pit mine power distribution, heavy‑load applications in coal preparation plants, coking‑plant integration, new‑energy system support, retrofitting of aging mines, and emergency backup systems. Adhering strictly to national and industry‑mandated standards—including GB 3836 (explosion‑proof standards), GB 50052 (power supply and distribution codes), MT/T 1095 (transformer standards for coal mines), and GB 50160 (fire‑protection requirements for the petrochemical industry)—and taking into account the distinct needs of various coal‑mining and mineral‑processing settings, we provide turnkey, fully implementable solutions tailored to each application.

Core Principles for Selection

Medium and Explosion-Proof Selection

Core red line: underground mandatory explosion-proofing

1. Underground Scene 2. Open-Pit Mine / Coal Preparation Plant 3. Surface Logistics

Energy Efficiency and Energy-Saving Selection

Amorphous alloy core transformer

Compliant with GB 20052-2020 Level 1 energy efficiency, the amorphous‑alloy core transformer (SCBH series) is the preferred choice for open‑pit mines, coal preparation plants, and support‑service areas, tailored to the mining industry’s demands for year‑round continuous operation and significant load fluctuations, thereby reducing life‑cycle energy consumption.

Typical Cases

Power Supply Renovation Project for the Mining Area of a Certain Mining Co., Ltd. in Qinghai Province

The power supply renovation project for the mining area of a certain mining limited liability company in Qinghai is located at the Sikuaoyangshengkutou mining site in Wutumeiren Township, Golmud City, Qinghai Province. The core substation equipment is supplied by Shaanxi Hante Zhidian Equipment Co., Ltd. The project’s key equipment includes: • One SZ18‑16000 kVA/110 kV oil‑immersed on‑load tap‑changing main transformer • Two SCB13‑200 kVA/10.5 kV dry‑type transformers, designed to operate in the extreme high‑altitude environment of 4,000 meters and to ensure reliable power supply for mining operations, including production, lighting, ventilation, and drainage—critical equipment for maintaining continuous production at this plateau‑level mine.
