摘　　要：针对大采高工作面在生产中存在着顶板压力大、片帮冒顶严重、支架失稳等问题,分析了大采高液压支架自动化控制技术需求,从工作面顶板、工作面煤壁管理、液压支架的防滑与防倾倒控制、多级护帮联动控制、液压支架智能跟机控制几个方面对大采高液压支架自动控制技术进行了研究:采用液压支架的自动移架控制和自动补压技术可使工作面液压支架对工作面顶板的支撑力达到预设值,从而实现对工作面顶板的有效管理;通过护帮板的姿态控制和支承压力控制可有效提高工作面煤壁的管理效率,防止片帮事故的发生;采用倾角传感器、行程传感器和激光传感器检测支架姿态,可实现工作面液压支架的伪斜自动控制;通过在护帮板上安装接近传感器实现多级护帮板的逻辑控制;采用红外传感器检测采煤机位置,按照采煤工艺实现大采高液压支架的跟机自动化控制。In view of problems of high roof pressure,serious spalling and roof falling and instable support in production of large height mining face,demands of automation control technology of the large mining height hydraulic support were analyzed.The automatic control technologies of large mining height hydraulic support were researched from roof,coal slip wall management of working face,anti-skid and anti-dumping control of hydraulic support,multi-level linkage control of face guard,intelligent following control of hydraulic support:the support force of hydraulic support on working face roof was reached setting load adopting hydraulic support automatic shift control and automatic pressure compensation technology,so as to realize effective management for the working face roof;management efficiency of coal wall on working face was effectively improved by attitude control and support pressure control of face guard,rib spalling accident was prevented;pseudo inclined automatic control of hydraulic support on working face was realized by using angle sensors,distance sensor and laser sensor to detect support attitude;logic control of multi-stage face guard was realized by installed proximity sensor on face guard;position detection of shearer was used infrared sensors,automatic following control of large mining height hydraulic support was realized according to the coal mining process.
