摘要
介绍了在煤层厚度较大,煤质硬度较高的工作面条件下,为了提高大功率电牵引采煤机截割能力所采取的改进措施,介绍的部分技术已在国产MG900/2100-GWD型采煤机上得到应用,并取得了较好的效果。
In order to improve the cutting capability of large power electric haulage shear,takes several measures such as improve cutting and haulage power of shear,cutting drum rotation and anti-vibration ability under the condition of thick seam and high coal hardness.Some of these technologies have been applied on MG900/2100-GWD shear.
