One Yuchai 12VCN 1000kW gas‑fired generator set is officially put into operation at the coal mine gas power project in Yangquan City, Shanxi Province. Running with on‑site extracted coal mine gas as fuel, this single 1000kW unit acts as core power‑generating equipment for the local mining area. It supplies steady and reliable power for underground mining production, gas drainage systems, mine ventilation equipment, safety monitoring facilities and auxiliary on‑site loads. The unit achieves harmless treatment and efficient resource utilization of drained coal mine gas, cutting methane emissions for the mine.
1.Background:
Yangquan Coal Mine Gas Utilization Project, Shanxi Yangquan is a major coal‑producing base in eastern Shanxi, rich in coal mine gas resources. Large volumes of coal mine gas are continuously extracted during underground coal mining. Direct venting of coal mine gas not only wastes available energy but also brings greenhouse‑gas risks and hidden safety hazards to the mine. The mountainous mining area features fluctuating gas concentration, high dust content and humid working conditions, which set high requirements for gas adaptability, continuous running stability and environmental resistance of gas generator sets. Local mines face high cost for purchasing grid electricity. This gas power project aims to convert drained coal mine gas into usable electric power for self‑consumption on site. It helps mines lower power expenditure, improve intrinsic safety level and realize green low‑carbon production.
2.Why Adopt Single 1000KW Yuchai 12VCN Gas‑Fired Unit
The Yuchai 12VCN 1000kW gas generator set is specially configured to match the gas output and power demand of Yangquan coal mines. Powered by 12‑cylinder V‑type gas engine, the model is optimized for coal mine gas with unstable concentration. It can dynamically adjust combustion status to maintain stable power output even when gas quality fluctuates. Targeted dust‑proof, moisture‑proof and anti‑corrosion treatment is applied to air intake assemblies, pipelines and control components to cope with heavy dust and humidity inside the mining zone. The skid‑mounted layout simplifies field installation and commissioning. Single‑unit configuration avoids complicated parallel control systems needed for multiple small‑size units, reduces spare‑part categories and daily maintenance workload for mine technicians, satisfying long‑time continuous operation requirements of mine gas power stations.

4.Operational Value Since Commissioning
After commissioning, the Yuchai 12VCN 1000kW gas‑fired unit realizes resource recycling of waste coal mine gas for Yangquan mine. It reduces methane release and lessens reliance on utility grid power, effectively lowering the mine's electricity cost. Optimized for local harsh mine environment, the unit keeps low failure rate during long‑term running and cuts long‑term OPEX. The project brings economic returns while improving mine safety performance, supporting low‑carbon transformation of local coal industry.
5.Frequently Asked Questions (FAQ)
Q: What fuel powers this Yangquan project unit?
A: It runs on on‑site drained coal mine gas. Supported by intelligent gas adaptive control system, the unit adjusts combustion parameters automatically against gas‑concentration variation to guarantee stable power generation.
Q: Can Yuchai 12VCN cope with Yangquan mine's dusty and humid environment?
A: Yes. It adopts high‑efficiency dust filtration, sealed structure and anti‑corrosion treatment. The customized design enables stable long‑term operation under high‑dust and humid mine conditions.
