液压技术由于具备传动力量大、体积小、操控方便等优点,在煤矿采煤中的应用非常广泛。文章介绍了煤矿的液压采煤机以及液压支架放顶煤采煤技术中液压技术的运用,希望此研究能够为煤矿生产中更好地利用液压技术、提高煤矿生产效率提供一定的参考和借鉴。 Because of its hydraulic power transmission, small size, easy operation and control, it is widely used in coal mining. This paper introduces the application of hydraulic technology in the hydraulic coal mining machine and hydraulic powered top coal caving mining technology. It is hoped that this research can provide some reference and reference for better utilization of hydraulic technology in coal mine production and improvement of coal mine production efficiency.
