| Abstract: | At the fully mechanized coal face with big mining height,the width determination of plastic zone is theoretical promotion of safe measures.Distortion and failure of the big mining height coal seam in fully mechanization was studied by field investigation and theoretical analysis with a 4.2m thick coal mine exploration site for the research.And the plastic zone of coal seam was exactly calculated. |
| Keywords: | fully mechanized coal mining with big mining height width of plastic zone numerical simulation |
