全国首个极薄煤层高效智能采煤机投入应用

Core Insights - The first ultra-thin coal seam high-efficiency intelligent mining machine in China has been successfully put into operation, developed by China Coal Technology & Engineering Group's Shanghai Research Institute [1][3][5] Industry Overview - China's thin coal seam resources account for approximately 20% of the total coal reserves, amounting to 3.5 billion tons, but only 7% of the total coal production comes from these resources [3] - As easily accessible medium-thick coal seams diminish, the urgent need to promote the mining of thin and ultra-thin coal seams has become a priority for the coal industry [3] Technical Innovations - The mining machine features an innovative suspension transmission system and dual-cutting motor structure, allowing it to operate flexibly in heights as low as 0.78 meters [6] - The development team utilized medium-voltage variable frequency technology to reduce the machine's size, enabling smooth operation in narrow and uneven tunnels [6] - The integration of inertial navigation systems and intelligent cutting algorithms allows the machine to automatically plan optimal paths, achieving centimeter-level operation and millimeter-level control [6] Operational Impact - The application of this equipment enables automatic cutting of ultra-thin coal seams, achieving a standard of unmanned operation with remote intervention [6] - If this technology is widely adopted across the country, it could unlock over 10 billion tons of ultra-thin coal seam resources, equivalent to creating 10 large coal mines, which is significant for ensuring China's energy security [6]
