摘要
孤岛工作面往往存在冲击地压的可能,而冲击地压的破坏性极大,严重威胁煤矿安全生产。棋盘井煤矿I020908工作面属于孤岛工作面,经冲击危险性评价,判定该工作面具有弱冲击危险性。为保证安全回采,在棋盘井煤矿I020908工作面冲击危险性评价基础上,针对I020908孤岛工作面制定相应的冲击地压防治设计,为工作面回采期间防冲工作的开展提供依据。
The possibility of rock burst often exists in isolated working face,and the destructive of rock burst was great,which seriously threatened the safety production of coal mine.The I020908 working face of Qipanjing Coal Mine belongs to isolated island working face.Through impact risk assessment,it was determined that the working face has weak impact risk.In order to ensure the safety of mining,based on the impact risk evaluation of I020908 working face in Qipanjing Coal Mine,the corresponding rock burst prevention design was formulated for I020908 isolated island working face,which provided the basis for the development of anti impact work during the mining period.
