Idea of whole design of unmanned fully-mechanized coal mining face and its implementation method

Unmanned or lee-manned fully-mechanized coal mining face is a core topic about coal mine safety.A view was pointed out that automatic coal mining should be pondered on from the whole fully-mechanized system,and fully-mechanized equipments should be classified into production equipment,auxiliary equipment and control center of coal mining face,whose control requirements were proposed.The composition of the control center of coal mining face and main functions of each part were emphatically described.The composition,system structure and characteristics of unmanned fully-mechanized coal mining face were introduced.It was believed that the unmanned fully-mechanized coal mining face could realize four-level monitoring and three-level control.
