Research and Application of High-efficiency Intelligent Coal Mining Machine for Rigid Coal Seam with Thickness of 1.7-2.5m
Abstract：To meet the demand for efficient mining of rigid coal seams with thickness of 1.7-2.5 m, the MG900/2360-WD high-efficiency intelligent electric traction coal cutter was developed. By analyzing the geological conditions and mining requirements of coal seams in the Mengxi mining area, key technologies of the coal cutter were innovatively researched and developed, including overall design optimization, high-efficiency cutting unit development, long-life travel system development, and intelligent monitoring and control. This significantly improved the power, traction speed, and reliability of the coal cutter. Industrial trials showed that the coal cutter meets the high production demand of 4 million tons per year under an average seam height of 2 m, with a machine availability rate of ≥99% and key components operating without failure for more than the designed service life, providing strong support for the construction of intelligent mines.
