Abstract: The research on the structure of Dongpo coal mine is of great importance to the prevention and control of mine water.The study is focus on the development rules of fold and fault,the relationship between the structure and the effect of stress according to the stress field analysis of regional structure and the mine construction statistics.The results show that the main structure inside the field are nearly EastWestward folds,faults and NE-NNE faults.Among them,the Danshuigou fault located the southern boundary of field was the first order structure,the fault and fold in the field were the second order tectonics. Danshuigou fault has a control effect on the structure formation in the field.
