Abstract：Taking the 210108 fully mechanized coal face in xinji as the research object ,established the mine pressure observation scheme under the condition of hard roof blasting weakening .Through the analysis of field measured data of the working face mine pressure appear characteristics ,the paper analyzes the characteristics of strata behaviors ,the laws of roof movement ,and distribu-tion laws of advancing abutment pressure .Meanwhile,the characteristics of support load during the first and periodic weighting of main roof are researched .The law of mine pressure was mastered under the condition of hard roof weakening ,Provide a basis for safe mining face.
