摘　　要：为实现综放工作面自动化放煤,通过计算机模拟分析不同采放比条件下最优放煤方案,应用工业以太网作为基础通信技术,将1 000 MB光纤环网技术应用于整个工作面,对于支架控制器、输送机、转载机、破碎机等静止设备采用有线方式接入网络;对于移动设备如采煤机不方便布线的设备,采用无线技术接入网络,实现工作面智能控制通信。首次提出分别在液压支架的顶梁腹板水平段、尾梁腹板处和支架控制器内安装放顶煤液压支架智能姿态耦合控制装置、放煤机构姿态控制装置和放煤记忆装置。通过放煤过程中有关信号的检测、传输、匹配,最终转化为执行动作实现自动化放煤。In order to meet safety and high efficiency, realize automate drawing, optimal scheme of caving coal was analyzed under the condition of different caving ratios by computer simulation.Applying the Industrial Ethernet as basic communication technologies, 1 000 MB optical fiber ring network technology was applied to the entire face.Some stationary equipments such as support controller, conveyor, re- versed loader, and crushers were switched on network by the method of wired.For mobile equipment such as shearer which was not conven- ient to be wired, access the network using wireless technology were switched on network to realize intelligent control communication in working face. It was firstly introduced that intelligent attitude control equipment coupled, bracket mounted caving intelligent attitude control equipment coupled, caving agency attitude control equipment and top-coal caving memory equipment was installed in top beam web hori- zontal section, at the end of the beam web and inside the controller of hydraulic support.Translates to perform actions to automatic caving was realized by the detection, matching and transmission of correlation signal.
