摘　　要：以煤层坚硬的顶底板组合条件即“两硬”条件下沿空巷道冲击地压为主要研究对象,调研分析了大同矿区冲击地压的影响因素和显现特征。通过对典型冲击地压矿井综合防治要点、监测预警体系实施情况和现场解危实践等进行分析,形成了以“两硬”条件下沿空回采巷道冲击地压危险区域的划分和以多参量监测预警体系为基础的冲击地压综合防治体系。研究成果可为“两硬”条件下沿空回采巷道采取有针对性的监测预警和动态调控措施提供依据。Rock burst along goaf roadway was taken as the main research object under the condition of“two hard”,namely the combined condition of hard roof and floor of coal seam,the influence factors and occurrence characteristics of rock burst in Datong mining area were investigated and analyzed.By analyzing the key points of integrated prevention and control of typical rockburst mines,the implementation of monitoring and early warning system and the on-site practice of relieving danger,a comprehensive prevention and control system of rock burst based on the division of dangerous area of rock burst and multi-parameter monitoring and early warning system of goaf roadway under the condition of“two hard”has been formed.The research results can provide a basis for taking targeted monitoring and early warning and dynamic regulation measures for goaf mining roadway under“two hard”condition.
