A total of 26 sets of Yuchai 12VCN 1000kW mine-gas generator sets have been fully delivered and successively put into operation across multiple mining areas of Henan Pingmei Shenma Group. Serving as core clean power equipment for the mine gas comprehensive utilization project, these units realize harmless treatment and efficient energy conversion of coal mine gas, providing stable and reliable power support for intelligent mining, mine auxiliary production and grid-connected power generation.
1. Project Background: Henan Pingmei Mining Area
As a key national coal energy base, Henan Pingmei Shenma Group features abundant coal mine gas reserves in its mining areas. Traditional direct venting of mine gas not only causes serious waste of clean energy resources but also brings potential safety hazards to underground mining and increases greenhouse gas emissions. To implement the graded and efficient utilization of mine gas, improve mine intrinsic safety, and promote green low-carbon transformation of the coal industry, Pingmei has built a full-cycle system of "gas drainage, pretreatment, efficient power generation and carbon emission reduction" across multiple mines. Relying on mature mine gas utilization technology, the group converts drained gas into usable electric power, realizing dual benefits of safety production and energy conservation and emission reduction. Against this background, Yuchai 12VCN professional mine-gas generator sets are fully deployed in batches to support the stable operation of distributed power stations in each mining area.
2. Why Adopt Yuchai 12VCN 1000kW Mine-Gas Generator Sets
Pingmei's multiple mining areas have complex gas supply conditions with frequent fluctuations in gas concentration and pressure, which puts forward extremely high requirements on the adaptability and stability of gas power generation equipment. The Yuchai 12VCN series gas engine is specially optimized for domestic coal mine working conditions, with strong tolerance to low-concentration and fluctuating mine gas, perfectly matching the graded gas utilization mode of Pingmei mining areas.
The batch delivery of 26 sets of 1000kW units adopts modular distributed layout, which can flexibly adjust the number of operating units according to the real-time gas output of each mine. This distributed configuration avoids the energy waste and operational risks caused by single large-unit operation, and facilitates independent operation, maintenance and management of each mining area power station. In addition, the units feature intelligent adaptive gas supply control, strong anti-interference ability and low failure rate, which can adapt to the long-term continuous operation requirements of mine power stations, effectively guaranteeing the continuity of mine gas treatment and power generation work.

4. Operational Value Since Commissioning
With the cumulative delivery and stable operation of 26 Yuchai 12VCN 1000kW mine-gas generator sets, Pingmei's multiple mining areas have achieved standardized and large-scale utilization of drained coal mine gas. The equipment effectively eliminates potential safety risks caused by gas accumulation in mines, turning waste gas into valuable electric power resources.
The modular distributed operation mode enables flexible capacity allocation for different mining areas, greatly improving the overall energy utilization efficiency. While ensuring safe and stable power supply for mining production, the project significantly reduces methane emissions, delivering remarkable economic, safety and environmental benefits. It also provides a replicable and mature green power solution for large-scale coal mine gas comprehensive utilization.
5. Frequently Asked Questions (FAQ)
Q: What are the core advantages of Yuchai 12VCN units for Pingmei's mining scenarios?
A: The 12VCN series gas engines are tailor-made for complex coal mine working conditions. They have outstanding adaptability to unstable mine gas concentration and pressure, solving the common pain points of insufficient power and unstable operation of traditional gas generator sets in mining areas.
Q: Why adopt 26 sets of 1000kW distributed configuration instead of large-capacity units?
A: Each mining area has dispersed gas output and inconsistent supply capacity. The small and medium-sized modular distributed layout supports independent operation of each mine, avoids overall shutdown risks caused by single unit failure, and simplifies daily maintenance and later capacity expansion.
Q: What environmental and economic benefits do these units bring?
A: The sets realize efficient recycling of waste mine gas, reducing greenhouse gas emissions and improving mine safety. The generated electric power can be used for self-use or grid connection, creating stable economic benefits while promoting the green transformation of the coal industry.
