| Abstract: | Combined with the basic situation of 74102 working face in Zhangshuanglou Coal Mine,the dangerous state of rock burst in working face and the dangerous degree of rock burst in each section are determined by the methods of overall qualitative,sectional grading and comprehensive evaluation.Comprehensive anti-scour technologies such as large diameter pre-pressure relief,roof deep hole pre-splitting blasting,coal seam high-pressure water injection and floor pressure relief in coal seam synthesis area were adopted.Through the analysis of microseismic monitoring data and field observation,the anti scour effect of this technology was better. |
