Key technology for intelligentization of thin coal seam fully mechanized mining face and its application
In response to the long-term problems of low equipment matching performance,low intelligence level,low economic benefits,and high labor intensity faced by the mining of thin coal seam working faces,a new intelligent unmanned mining mode of"ground planning coal mining,automatic equipment execution,and unmanned operation in the face"was been constructed during the production of working faces,with ground process scheduling decision-making and automatic execution of underground equipment based on decision-making.We established a complete set of key technologies for intelligent mining of thin coal seams,with the ground control center as the core and supplemented by a 10 Gigabit network communication platform above and below the mine,coal mining machine planning and cutting,hydraulic support master-slave scheduling,mounted audio and video devices,inspection robots,cable dragging,and the integration of three positions.According to the industrial practice,this mode can reduce the number of workers in the working face from 3 to unmanned during production,and ensure safety if no one is present;and increase production efficiency from 12 to 14 per day,reaching a maximum of 16,with an average increase of over 17%.
