Application Research on Intelligent Mining Technology of Coal Seam
Aiming at the problem of insufficient application of intelligent mining technology due to the lack of close integration between theory,technology,and practice in fully mechanized coal mining,numerical simulation method is adopted to optimize and analysis of intelligent caving technology in a coal mine.Through the study of the evolution of the stress field during the fully mechanized top coal caving mining of thick coal seams in a certain coal mine,the mechanism of top coal fragmentation during fully mechanized top coal caving mining,and the transportation and release laws of top coal during fully mechanized top coal caving mining,an intelligent overall control structure for coal caving has been developed.Through numerical simulations of the single wheel sequence,segmented sequence,and single wheel interval,it was found that the single wheel interval coal release method has the highest release rate and recovery rate,and is most suitable for this coal mine.According to the above optimization method for engineering practice analysis,the number of underground workers in coal mines has significantly decreased,the mining efficiency has significantly improved,and the economic benefits of coal mining enterprises have been enhanced.This has profound significance for the research of intelligent coal seam mining technology.
