Ten Yuchai 16VC 2000kW containerized diesel generator sets delivered and commissioned by Zhaojin Mining Industry Co., Ltd. (01818.HK) in 2021 - a 20MW fleet of emergency standby power distributed across the group's gold mines, each unit directly connecting to mine 10kV distribution to safeguard underground life-safety loads (ventilation, dewatering, hoisting). Zhaojin Mining is a Hong Kong-listed gold producer headquartered in Zhaoyuan, Shandong - China's "Gold Capital".
1. Background: Zhaojin Mining and Zhaoyuan
Zhaojin Mining Industry Co., Ltd. (招金矿业, stock code 01818.HK) is a professional gold producer, established in 2004 and listed on the Hong Kong Stock Exchange in 2006. It is the core mining subsidiary of Shandong Zhaojin Group, headquartered in Zhaoyuan, Shandong - officially "China's Gold Capital" (中国金都).
In 2024 the group produced 26.45 tonnes of gold (18.34 t mineral gold) and reported revenue of RMB 11.55 billion with net profit of RMB 1.85 billion. Its gold resources total 1,446 tonnes (JORC). The group operates numerous mines at home and abroad - including Xiadian, Dayingezhuang, Canzhuang and the Haiyu (sea-area) gold mine in Shandong, plus assets in West Africa (Abuja, Côte d'Ivoire) and Fiji. Underground mining is the backbone of the business.
2. Why a 10-Unit 20MW Fleet
Every underground mine depends on three life-safety loads: ventilation (通风), dewatering (排水) and hoisting (提升). A simultaneous loss of external power threatens personnel and the mine itself. A single large mine - let alone a group with many mines - needs dependable emergency (third) power at each site, plus spares for maintenance so protection is never compromised.
In 2021 Zhaojin Mining deployed ten Yuchai 16VC 2000kW containerized sets - a 20MW fleet. The containerized design allows standardized, rapid deployment across multiple mines and easy relocation as pits develop. N+1 redundancy is built in: with ten units, several can be down for service while the rest still cover the critical loads group-wide.

4. Operational Value Since Commissioning
Since 2021 the fleet has given the group a reusable, standardized power-resilience layer: each mine can draw on containerized standby units for safe evacuation and flood control during external outages.
The containerized, standardized design simplifies training, spare-parts management and cross-site deployment - fitting Zhaojin's "gold has a price, life is priceless" (黄金有价,生命无价) safety culture. For a multi-mine group, a shared 20MW containerized standby fleet is a cost-effective alternative to building full dedicated backup at every single shaft.
5. Frequently Asked Questions (FAQ)
Q: What is the Zhaojin Mining 2000kW container generator set?
A: Ten Yuchai 16VC 2000kW containerized diesel generator sets deployed by Zhaojin Mining in 2021 - a 20MW fleet for emergency standby of underground life-safety loads across its gold mines.
