Abstract: The measured pressure in working face 12106 in Shangwan coal mine is analyzed,the roof movement parameters are calculated based on the characteristics of working face 12106.Besides that,the roof structure model of 12106 working face is established.The above research results can provide foundation data for predicting the mine pressure regularity of the new 12401 working face.

Key words: 12106 working face, Roof movement parameters, Roof structure model
