摘　　要：针对综采工作面应用广泛的全截深双向割煤工艺特点,提出了一种涵盖中部跟机自动化、机头跟机自动化和机尾跟机自动化3个阶段的综采工作面液压支架跟机自动化工艺。依据液压支架动作类型及跟机动作距离,对中部跟机自动化工艺流程进行了分析;结合液压支架动作流程及采煤机运行轨迹,将机头、机尾跟机自动化工艺流程细分为割透煤壁、首次反复刹底、斜切进刀、割三角煤、二次反复刹底、向中部割煤6个阶段。应用表明,该工艺有效提高了液压支架跟机自动化水平。In view of characteristics of full cutting depth bidirectional cutting technology which was widely used in fully-mechanized coal mining face,a following automation technology of hydraulic support on fully-mechanized coal mining face was put forward,which included three stages:middle following automation,head following automation and tail following automation.According to action type of hydraulic support and following action distance,technology process of the middle following automation was analyzed.Combining with action flow of hydraulic support and running track of shearer,technology process of the head and tail following automation was divided into six stages:cutting through coal wall,first repeatedly braking bottom,oblique cutting feed,cutting triangular coal,secondary repeatedly braking bottom and cutting coal toward the middle.The application results show that the technology effectively improves following automation level of hydraulic support.
