Based on thin bedrock in shallow buried deep working face and violent roof weighting, support suitability and 3103 mine pressure law of shallow buried deep working face were studied on the basis of rock pressure mearseanment. Average first weighting interval of working face was 11.13m, first weighting interval in middle part was larger than its sides;  average periodic weighting length was 12.9m; average dynamic factor was 1.47, peak of ground pressure strength was within holder rated operation resistance range. Setting load was obviously low which was not conductive to roof maintenance. Average maximum pressure of working face bracket right column was much bigger than left one, and had poor balanced load performance.
