Amid the in-depth transformation of the coal industry towards green and intelligent development, the compressed air system, as a core power source for the safe production of coal mines, its energy efficiency and operational stability directly determine the production efficiency of mines and serve as a critical bottom line for safeguarding safe production. In January 2026, Bolaite’s BLT-350A II/10KV two-stage compression air compressor was successfully put into operation at a domestic coal industry Co., Ltd. Relying on its core advantages of Class 1 energy efficiency, high air delivery and low energy consumption, it has built an efficient, stable and energy-saving power support system for the two core processes of the coal mine’s nitrogen generation system and underground gas injection.
The Bolaite two-stage compression series deployed this time undertakes the dual core air supply tasks in coal mine production: on the one hand, it delivers clean and stable compressed air raw materials to the on-site nitrogen generation system, ensuring the continuous supply of high-purity nitrogen and laying a solid foundation for safety processes such as the inerting of underground goafs, gas explosion prevention and fire control; on the other hand, it directly serves underground gas injection operations, providing continuous power for coal seam permeability enhancement and precise underground pressure regulation, and boosting the efficient progress of coal mining processes.

In the coal production process, the Bolaite two-stage compression series is equipped with the ICONS system. Relying on the Internet of Things and intelligent algorithms, the system can collect real-time core data such as pressure, temperature and energy consumption of the two-stage compression air compressor, and realize dynamic regulation in combination with the air demand of coal mining, washing, ventilation and other processes. It not only adapts to the high-load and continuous air consumption characteristics of coal mines, but also raises the operational energy efficiency of the air compressor to the Class 1 standard, significantly reducing the power consumption of the underground air supply link.
Meanwhile, the ICONS system features remote monitoring and fault early warning functions, which can identify equipment abnormalities in advance and push alarm information, avoiding the suspension of coal mining operations caused by air supply interruption. It is adapted to the harsh working conditions underground in coal mines, enabling the operational stability of the two-stage compression equipment to form an efficient synergy with the continuity of coal production.

According to on-site usage feedback, since the commissioning of Bolaite’s BLT-350A II/10KV, the equipment has operated continuously without faults with stable discharge pressure, fully adapting to the coal mine’s 24/7 uninterrupted production rhythm; its low-speed design has greatly reduced the equipment’s operating noise, optimizing the working environment of the mining area, and the Class 1 energy efficiency has enabled the customer to achieve a considerable reduction in electricity costs, verifying the value of two-stage compression technology with actual data.
In the future, relying on the group’s technological advantages, Bolaite will continue to deepen its research on the air compressor demands of industrial fields such as coal and chemical industry, and constantly iterate its two-stage compression products and solutions. With higher energy efficiency, better performance and more comprehensive services, Bolaite will empower more industrial enterprises to achieve the production goals of “energy conservation, cost reduction, safety and high efficiency”, and bring the energy-saving dividends of two-stage compression to more industry scenarios.
