Status and Outlook of Key Technology for Automation Coal Mining Face in Thin Seam

TIAN Cheng-jin(Beijing Tiandi-Marco Electro-Hydraulic Control System Company Ltd.,Beijing 100013,China)  
According the automatic coal mining face with a coal shearer in a thin seam and the automatic coal mining face with a coal plough in a thin seam,a brief analysis and summarization was conducted on the application status of the related automatic key technology and the restricted factors.An analysis was conducted on the coal and rock interface identification,the automatic lining technology of the coal mining face equipment,the posture detection and control technology,the plough head detection technology,the plough head control technology and other automatic mining key technology needed to be broken through in the present automatic coal mining face in China.Some technical difficulties needed to be solved in the next development of the automatic coal mining face were provided.The paper summarized the present study status of those technical difficulties and provided the further study orientation.
