Cause Analysis and Prevention on Mine Strata Pressure Bumping from Fully Mechanized Top Coal Caving Mining at Steep Inclined High Level Stage of Shallow Seam

According to the special mine strata pressure bumping occurred from Tiechanggou Mine with a mining depth of 155 m, the paper had an analysis on the mine pressure behavior conditions and features of the mine strata pressure bumping occurred from the fully mechanized top coal caving mining at the steep inclined hig h level section in seam with a shallow depth of the mine.Meanwhile the geological factors and production factors affected to the mine pressure bumping were analyzied. The results showed that the coal and rock bumping tendency, the mining depth and geological structure, the super support pressure in front of the coal mining face, the coal mining face location and the mining sequences, the mining method, the coal mining face advancing speed, the blasting and other factors could cause the mine pre ssure bumping occurred.With the analysis on the cause of the mine pressure bumping occurred, the suitable measures to prevent and control the mine strata pressure bumping in the mine were summarized.
