Shaanxi Coal Group West Coal Machinery Co., Ltd. Launches China's First Set of High-Performance 8-meter Large Mining Shearer

Shang Jianxuan, deputy general manager of Shaanxi Coal Chemical Industry Group, said that the first domestically-produced high-performance 8 m high coal mining machine is a major achievement in systematic R&D, manufacturing and manufacturing of domestic imported products in the field of shearers in recent years. The replacement of the complete machine for imported shearers was achieved, breaking the monopoly of imported technology, reducing the cost of equipment procurement and operation of coal production enterprises, ensuring the technical excellence of equipment and accessories, and improving the economic efficiency of coal mining enterprises. West Coal has made major breakthroughs in the design, process, manufacturing, quality, and other aspects of the standard import equipment, further improving the ability of shearer design and processing, marking a new stage in high-end manufacturing.

At the meeting, the Expert Appraisal Committee organized by China Coal Industry Association heard technical reports from the project team and reviewed related technical documents. After questioning, defending and discussing, it was agreed that the high-performance 8 m high coal mining machine developed by West Coal Machinery Co., Ltd. is a domestic initiative and the overall performance index has reached the international advanced level, which can meet the mining requirements of the 8 meters high mining face. , agreed to pass the factory assessment and conduct downhole industrial tests.

Zhang Yong, president of China Coal Machinery Industry Association, read out the comments on the first set of domestically-made high-performance 8 m high coal mining machine on behalf of the expert review committee: First, the first 8-meter high-pit mining machine for coal mining. Perfect function, automatic function interface, memory cutting function. Superior performance, good stability, high reliability, can meet the production requirements of more than 10 million tons of annual production surface; Second, the development of new high-strength shell materials, research and development of high-performance gear and rack wheel deep carburizing technology and processing Process, etc., design and process technology are at the advanced level; Third, the control system is based on high-reliability industrial computer, using CAN bus, DCS distributed control, and enhanced DTC frequency conversion control to make traction matching more accurate.

Yang Peng, chairman of Shenhua Shendong Company, introduced the background, process, and achievements of the first domestically developed high-performance coal mining machine with a height of 8 meters, and proposed the development of domestic high-end shearers. Constructive comments and suggestions.

Peng Jianxun, vice president of China Coal Industry Association made a speech at the meeting. He said that China’s first high-performance coal mining machine with a high performance of 8 meters is complex, difficult to research, has a high degree of correlation, complete sets, and the technology has reached the international advanced level. It is an independent R&D capability and comprehensive strength of large-scale coal equipment in China. The concrete manifestation of international competitiveness is of great significance for ensuring the safe, efficient, green, and intelligent mining of large-scale modern coal mines and further improving the level of localization of major technical equipment for coal. He hopes that West Coal Machinery Co., Ltd. and Shenhua Shendong Co., Ltd. will be closely integrated and tested and continuously improved. With the practice of coal mining and the innovation of key technologies, the company will truly build the brand of international coal machinery.

The first domestic launch of the high-performance 8m high mining coal winning machine was successfully launched to achieve high-yield and high-efficiency mining of extra-thick coal seams, reduce the cost of spare parts purchase, solve the procurement bottlenecks of spare parts, reduce labor intensity, improve mining efficiency and resource recovery, and improve China's The core competitiveness of coal mining machinery and equipment manufacturing industry is of great significance and is another major breakthrough in the process of localization of coal mining machines imported from China.
