摘要: 针对综采工作面采煤机和液压支架协同控制效率较低问题，基于采煤机记忆割煤和液压支架跟机自动化控制技术，提出了一种综采工作面采煤机和液压支架协同控制技术。依据综采工作面生产作业工艺，对采煤机和液压支架作业工序进行划分后重新匹配，生成采煤机和液压支架协同工序，各工序中通过协同控制逻辑实现对采煤机牵引方向、速度和液压支架跟机动作的协同控制。应用结果表明，与人工干预控制模式相比，该技术降低了采煤机和液压支架控制对人工干预的依赖性，提高了综采工作面自动化水平，为实现无人化开采提供了技术支撑。Abstract: Aiming at low cooperative control efficiency of shearer and hydraulic support on fully-mechanized coal mining face, a cooperative control technology of shearer and hydraulic support on fully-mechanized coal mining face was proposed based on technologies of shearer memory coal cutting and automatic control of hydraulic support following. According to production process of fully-mechanized coal mining face, operation processes of shearer and hydraulic support are divided and then re-matched to generate cooperative operation process of shearer and hydraulic support. In each operation process, cooperative control of direction and speed of shearer traction and hydraulic support following movement are realized through cooperative control logic. The application results show that compared with manual intervention control mode, the technology reduces dependence of shearer and hydraulic support on manual intervention, improves automation level of fully-mechanized coal mining face, and provides technical support for realization of unmanned mining.
