    • 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.
